Upgrading Universal Data Mover Gateway

Upgrading UDMG refers to the increase of a currently installed pre-2.0.x Version, Release, or Modification level of UDMG (1.5.x, 1.4.x, 1.3.x) to UDMG 2.0.x.

As a precautionary measure, it is highly recommended that you back up the UDMG database prior to upgrading.

Upgrading from a pre 2.0 UDMG release

If you are upgrading an installation of UDMG from any release before 2.0.0.0, the following changes must be reviewed carefully.

License Key

Starting with UDMG version 2.0, a license key must be provided to enable file transfers.

Contact your Stonebranch representative or Customer Support to receive the license key before upgrading to version 2.0 or later.

Shared Account

(1) Local Accounts are converted to Shared Accounts

Before this change, a local account was only defined for a given local server and not allowed to have the same account for multiple protocols. For instance, to allow a partner to transfer files over SFTP and FTP, it was required to have both an SFTP and FTP local server, each with their own local account. Each account was then maintained independently, which created additional overhead in configuration and maintenance (password or key updates). A shared Account is created once and can be assigned to several Local Servers, sharing the same login, password, and authentication records.

A migrated account has the following characteristics:

Linked to the Local Server that owned the Local Account. The new Shared Account can later be assigned to other servers.
Member of the same Business Services as the Local Server. The Shared Account membership to Business Services can be modified later but must retain compatibility between Server memberships and Shared Account memberships
Account name is composed of the original server name and the login: <local_server name>-<local_account login>,for example, if the local account has a login of "common" and belongs to the local server "sftp", the new account name is "common-sftpr". The Share Account name can be edited later, it is only for internal use and does not affect the login that is used for authentication.
UDMG 1.5 local account

UDMG 2.0 migrated shared account

Enabled by default.

(2) New permission for Shared Account management

A new User and User Group permission, "sharedAccount", is created for the management of Shared Accounts.
The UDMG users and user groups are assigned these permissions by copying the existing server permissions. The refinement of server and sharedAccount permissions for the Users and User Groups can be done after the migration.
For example, if a UDMG user has server read and write permission, it is allowed to manage servers and local accounts. With the migration, it obtains also the sharedAccount read and write permissions to continue the management of accounts.

Start parameters

The start parameters for several services have changed.

Please review the start scripts, the following modules now require a 'start' command to begin in server mode.

udmg-auth-proxy.exe start -f configuration_file

udmg-agent-client.exe start -f configuration_file

udmg-agent-server.exe start -f configuration_file

Without it, they will only display the command line usage information.

In addition, a 'test' command allows the syntax of the configuration file to be verified without starting the server.

New configuration parameter with UDMG 2.0.0.0

Configuration Parameters

UDMG Server

Adds new database timeout option

[database]
; Threshold before warning for long-running queries, the default is 10 seconds
WarningTimeout=10s

Adds a parameter to disable the implicit assignment of Transfer Rules. Before this change, a Transfer Rule was allowed for all servers, partners, and accounts right after creation. It was only restricted after an explicit assignment (whitelisting) to at least one server, partner, or account. The prior functionality created confusion and allowed unauthorized access to files and folders for third-party accounts during the time between the rule creation and its explicit assignment. The change allows the functionality to be disabled with the new UDMG Server configuration parameter ExplicitRuleAssignment. When set to true, a Transfer Rule is only effective when it is explicitly linked with the intended target (local server, remote partner, remote or local account).

[rule]
; Disables global rules, requiring rules to be explicitly allowed to be used.
; ExplicitRuleAssignment = false

UDMG Admin UI

The recommended security setting for NGINX have been modified, with the inclusion of the following header directives. Please review the sample configuration on Installing NGINX Server page.

    # Server Banner
    server_tokens off;
 
    # DEPRECATED Security Headers
    add_header X-XSS-Protection "0";
    add_header X-Frame-Options "SAMEORIGIN";
 
    # Security Headers
    add_header Content-Security-Policy "frame-ancestors 'self'";
    add_header X-Content-Type-Options nosniff;
    add_header Referrer-Policy "strict-origin";
    add_header Strict-Transport-Security 'max-age=31536000; includeSubDomains; preload';
    add_header Permissions-Policy "geolocation=(),midi=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),fullscreen=(self),payment=()";
    add_header X-Permitted-Cross-Domain-Policies none;
 
    location /service/ {
      proxy_pass         http://udmg_auth_proxy/;
      proxy_set_header   X-Real-IP       $remote_addr;
      proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
    }

Agent Proxy Client

The section for the configuration of the target UDMG Server is renamed from [gateway] to [server].
New secure option to support HTTPS for the connection to the UDMG Server API

[server]
# UDMG Server Hostname or IP, and port
hostname = "localhost"
port = "8080"
# UDMG API protocol, set to true to select https, default is false for http
secure = false
# UDMG Server Username/Password
username = "admin"
password = "admin_password"

Upgrading from a pre 1.3 UDMG release

Note

If you are upgrading an installation of UDMG from any release before 1.3.0.0, you must uninstall the older version before installing the new version.

Migration from releases before 1.2.1.1 (0.7.1-sb.3) is not supported anymore.

The binaries, services, configuration parameters, and environment variables have changed, and this does not allow for a standard upgrade.

Category	Prior releases	Release 1.3
UDMG Admin UI assets	C:\UDMG\nginx\mft	C:\UDMG\nginx\udmg
Environment variables	WAARP_GATEWAY_ADDRESS MFT_AUTH_PROXY_CONFIG MFT_AGENT_PROXY_CONFIG	UDMG_SERVER_ADDRESS UDMG_AUTH_PROXY_CONFIG UDMG_AGENT_CONFIG

It may be required to modify the work and data directories ownership or access rights and to update UDMG Server transfer rules to use new paths.

The configuration files must be reviewed and compared between the old and new versions.

Special attention is required for the AESpassphrase parameter for UDMG Server. It must be the path for the file that was used by the previous release and must be accessible by the new service user. It is recommended to set an absolute path in the configuration file.

Pre-Installation / Upgrade Backups

Make sure to have a backup of the configuration files as it optimizes the time it takes you to get up and running after upgrading.

C:\UDMG\UDMG Server\server.ini C:\UDMG\UDMG Auth Proxy\config.toml C:\UDMG\UDMG Agent\agent\agent.toml C:\UDMG\UDMG Agent\client\client.toml

Release Migration

The UDMG release version is stored in the database to ensure the data structure is compatible with the version of the UDMG components.

After upgrading the component binaries and before starting the UDMG Server it is required to perform the release migration step.

The udmg-server "migrate" command handles the necessary database updates and the setting of the internal version.

C:\UDMG\UDMG Server>udmg-server migrate /?
Usage:
  udmg-server [OPTIONS] migrate [migrate-OPTIONS] [version]

Help Options:
  /?                Show this help message
  /h, /help         Show this help message

[migrate command options]
      /c, /config:  The configuration file to use
      /d, /dry-run  Simulate the migration but does not commit the changes
      /l, /list     List Migrations
      /f, /file:    Writes the migration commands into a file instead of sending them to the database
      /v, /verbose  Show verbose debug information. Can be repeated to increase verbosity

[migrate command arguments]
  version:           The version to which the database should be migrated

The configuration file is to be used for the server mode, with the parameter for accessing the target database.

To get the list of supported target versions, use the list parameter. The last value is the release version of the udmg-server and the default target version. The current version of the UDMG database structure is shown with the [DATABASE] tag:

C:\UDMG\UDMG Server>udmg-server migrate /c "C:\UDMG\UDMG Server\server.ini" /list 
0.7.1-sb.3
1.3.0
1.3.1
1.3.2
1.4.0
1.4.1
1.5.0 [DATABASE]
2.0.0
2.0.1 [DEFAULT]

It is recommended to set the verbose parameter (3 times) to follow the progress. If not specified on the command line, the target version is the latest release number.

Upgrading Universal Data Mover Gateway for Windows

Step 1	Contact your Stonebranch representative or Customer Support to receive the software binaries.
Step 2	Perform the recommended backup of configuration files.
Step 3	Stop the components services. The exact steps depend on the system architecture and the deployed components, for example: On the main UDMG host: `C:\UDMG\nginx>nginx-service.exe stop` `C:\UDMG\UDMG Auth Proxy\udmg-auth-proxy-service.exe stop` `C:\UDMG\UDMG Server\udmg-server-service.exe stop` `C:\UDMG\UDMG Agent\client\udmg-agent-client-service.exe stop` On the Proxy host: `C:\UDMG\UDMG Agent\agent\udmg-agent-server-service.exe stop`
Step 4	Upgrade the UDMG component binaries by copying the release files to their target location: On the main UDMG host: `copy udmg-server.exe "C:\UDMG\UDMG Server\udmg-server.exe"` `copy udmg-client.exe "C:\UDMG\UDMG Server\udmg-client.exe" copy icap-client.exe "C:\UDMG\UDMG Server\icap-client.exe" copy udmg-auth-proxy.exe "C:\UDMG\UDMG Auth Proxy\udmg-auth-proxy.exe" copy udmg-agent-client.exe "C:\UDMG\UDMG Agent\client\udmg-agent-client.exe"` On the Proxy host:`copy udmg-agent-server.exe "C:\UDMG\UDMG Agent\agent\udmg-agent-server.exe"` Upgrade the UDMG Admin UI: `C:\UDMG\nginx> move udmg udmg_BACKUP` `C:\UDMG\nginx> cd udmg` `C:\UDMG\nginx\udmg> tar -x -f "udmg-admin-ui-2.0.1.1.build.67.zip"`
Step 5	Perform the release migration.
Step 6	Review the component configuration files. Refer to each component installation section below for the list of parameters. On the main UDMG host: `C:\UDMG\UDMG Server\server.ini C:\UDMG\UDMG Auth Proxy\config.toml C:\UDMG\UDMG Agent\client\client.toml` On the Proxy host: `C:\UDMG\UDMG Agent\agent\agent.toml`
	Reinstall the components services to apply the changes for the start parameters. The exact steps depend on the system architecture and the deployed components, for example: On the main UDMG host: `C:\UDMG\UDMG Server\udmg-server-service.exe uninstall` `C:\UDMG\UDMG Auth Proxy\udmg-auth-proxy-service.exe uninstall` `C:\UDMG\nginx\nginx-service.exe uninstall` `C:\UDMG\UDMG Agent\client\udmg-agent-client-service.exe uninstall` `C:\UDMG\UDMG Server\udmg-server-service.exe install` `C:\UDMG\UDMG Auth Proxy\udmg-auth-proxy-service.exe install` `C:\UDMG\nginx\nginx-service.exe install` `C:\UDMG\UDMG Agent\client\udmg-agent-client-service.exe install` On the Proxy host: `C:\UDMG\UDMG Agent\agent\udmg-agent-server-service.exe uninstall C:\UDMG\UDMG Agent\agent\udmg-agent-server-service.exe install`
Step 7	Start the components services. The exact steps depend on the system architecture and the deployed components, for example: On the Proxy host: `C:\UDMG\UDMG Agent\agent\udmg-agent-server-service.exe start` On the main UDMG host: `C:\UDMG\UDMG Server\udmg-server-service.exe start` `C:\UDMG\UDMG Auth Proxy\udmg-auth-proxy-service.exe start` `C:\UDMG\nginx\nginx-service.exe start` `C:\UDMG\UDMG Agent\client\udmg-agent-client-service.exe start`

Installing and Configuring the Components

Note

Starting with UDMG version 2.0, a license key must be provided to enable file transfers.

Contact your Stonebranch representative or Customer Support to receive the license key before installing version 2.0 or later.

UDMG Server

Create a directory C:\UDMG\UDMG Server
Copy the binaries as udmg-server.exe and udmg-client.exe
Create the configuration file C:\UDMG\UDMG Server\server.ini with the following parameters:

Note

The lines starting with a colon ';' or a hash '#' are comments, describing the option of showing the default value.

The parameters must be adapted to your environment, in particular:

global section: GatewayHome
log section: LogLevel, LogTo, LogPath
admin section: Host, Port
database section: Type, Address, Name, User, Password

Note

About the log section:

The DEBUG and TRACE log levels are not recommended for production environments.
The detailed log feature (distinct log file for each transfer) is disabled when the log level is set to ERROR or CRITICAL.

Note

There are several ways to write a file or folder Windows path that is compatible with the supported INI format by udmg-server.

Valid syntaxes:

LogPath = "C:/UDMG/UDMG Server/logs"
LogPath = "C://UDMG//UDMG Server//logs"LogPath = "C:\\UDMG\\UDMG Server\\logs"
LogPath = C:\UDMG\UDMG Server\logs
LogPath = C:/UDMG/UDMG Server/logs

The first one, with the quotes and the forward slash, is recommended.
The following is an invalid syntax and raises an error message: cannot load server config: failed to parse the config file: cannot parse configuration: :<line number>: invalid syntax
LogPath = "C:\UDMG\UDMG Server\logs"

UDMG Agent Proxy

The UDMG Agent Proxy client is installed inside the LAN, typically on the same host as UDMG Server.
The UDMG Agent Proxy Server is installed on the Proxy host, typically in the DMZ.

Agent Proxy Server Configuration

Create a directory C:\UDMG\UDMG Agent\agent
Copy the binary as udmg-agent-server.exe

Generate a SSH Key for the service.
For example with the ssh-keygen tool that is provided by Windows OpenSSH tools (Key-based authentication in OpenSSH for Windows), or by 3PP packages like Copssh - OpenSSH for Windows or Portable Git for Windows.

C:\> ssh-keygen -t rsa -q -N "" -f "C:\UDMG\UDMG Agent\agent\agent_key"

If OpenSSH is not installed or not available, the PuTTY tool can be used instead.

Use PuTTYgen to generate a key pair for the agent, more detailed instructions can be found here: Using public keys for SSH authentication.

After generating the key, export it with OpenSSH format:

Create a configuration file as C:\UDMG\UDMG Agent\agent\agent.toml

Note

The Windows paths in the TOML configuration file must be specified either in UNIX-style, using forward slashes '/', or with double backslashes '\\'.

For example:

ssh_key = "C:/UDMG/UDMG Agent/agent/agent_key"

ssh_key = "C:\\UDMG\\UDMG Agent\\agent\\agent_key"

[agent]
# UDMG Agent Server Hostname or IP, and port hostname = "0.0.0.0"
port = "2222"
# path to the SSH private key file
ssh_key = "C:/UDMG/UDMG Agent/agent/agent_key"
# path to the SSH public key file
ssh_key_pub = "C:/UDMG/UDMG Agent/agent/agent_key.pub"# Agent Service User and password username = "udmg"
# Service Password
password = "61ee8b5601a84d5154387578466c8998848ba089"

The username and password keys are used for the UDMG Agent Client authentication to the UDMG Agent Server.

Agent Proxy Client Configuration

Create a directory "C:\UDMG\UDMG Agent\client"
Copy the binary as udmg-agent-client.exe

Create a configuration file as "C:\UDMG\UDMG Agent\client\client.toml"

[client]
##########################################################################################
# Configuration for the tunnel between UDMG Agent Proxy Client and UDMG Agent Proxy Server
##########################################################################################

# UDMG Agent Service User and password
username = "udmg"
password = "61ee8b5601a84d5154387578466c8998848ba089"

# 'ttl' is the interval between connection attempts to the UDMG Agent Server, default is 15 seconds.
ttl="15s"

# 'idle_timeout' is the amount of time that the Agent Proxy will allow a connection to exist
# with no upstream or downstream activity. The default idle timeout if not otherwise specified is 10 minutes.
idle_timeout = "10m"

[client.api]
##########################################################################################
# Configuration for the Admin API of the UDMG Agent Proxy Client: http://0.0.0.0:port/api
##########################################################################################
# port number, no default
port = "2280"
# API basic authentication credentials, no default
username = "api_user"
password = "api_password"
# 'debug_port', when specified, will enable the HEAP Profile dump export.
# This is provided for monitoring and troubleshooting and is not recommended for production.
# When enabled the head profile dump can be generated at http://127.0.0.1:debug_port/dump
#debug_port = 6060

[server]
##########################################################################################
# Configuration for accessing the UDMG Server Admin API
# UDMG Agent Proxy will list the available local servers to setup the forwarding services.
# The API user must have 'Servers read' permission
##########################################################################################
# UDMG Server Hostname or IP, and port
hostname = "localhost"
port = "18080"
# UDMG API protocol, set to true to select https, default is false for http
secure = false
# UDMG Server API user credentials
username = "admin"
password = "admin_password"

The username and password keys in the '[client]' section are used for the UDMG Agent Client authentication to the UDMG Agent Server.
