For the UDMG Web Transfer Client, please refer to UDMG Web Transfer Client for Windows Installation.

Upgrading Universal Data Mover Gateway

Upgrading UDMG refers to the increase of a currently installed pre-1.4.x Version, Release, or Modification level of UDMG (1.3.x, 1.2.x, 1.1.x, 1.0.x) to UDMG 1.4.x.

Note

If you are upgrading an installation of UDMG from any release prior to 1.3.0.0, you must uninstall the older version before installing the new version.
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_PROXY_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 will optimize 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 the one that will be used for the server mode, with the parameter for accessing the target database.

To get the list of supported target version, use the list parameter. The last version is the release version of the udmg-server.

C:\UDMG\UDMG Server>udmg-server migrate /c "C:\UDMG\UDMG Server\server.ini" /list 
0.7.1
0.7.1-sb.1
0.7.1-sb.2
0.7.1-sb.3
1.3.0
1.4.0

It is recommended to set the verbose parameter (3 times) to follow the progress.

C:\UDMG\UDMG Server>udmg-server migrate /c "C:\UDMG\UDMG Server\server.ini" /v /v /v 1.4.0
[INFO ] Migration: Starting upgrade migration...
[INFO ] Migration: Applying migration 'Bump database version to 1.4.0'

After the migration, the service for UDMG Server can be started.

Upgrading Universal Data Mover Gateway for Windows

Step 1	Contact your Stonebranch representative or the 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: `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-proxy-client-service.exe stop` `C:\UDMG\UDMG Agent\agent\udmg-agent-proxy-server-service.exe stop`
Step 4	Upgrade the UDMG component binaries by copying the release files to their target location: `sudo cp udmg-server.bin /opt/udmg/bin/udmg-server` `sudo cp udmg-client.bin /opt/udmg/bin/udmg-client` `sudo cp udmg-auth-proxy.bin /opt/udmg/bin/udmg-auth-proxy` `sudo cp udmg-web-transfer.bin /opt/udmg/bin/udmg-web-transfer` Upgrade the UDMG Admin UI: `mv /opt/udmg/var/www/udmg /opt/udmg/var/www/udmg_BACKUP unzip -d /opt/udmg/var/www/udmg/ 'udmg-admin-ui-1.4.0.0 build.6.zip' chown -R root:udmg /opt/udmg/var/www/udmg`
Step 5	Review the component configuration files. Refer to each component installation section below for the list of parameters. `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`
Step 6	Perform the release migration.
Step 7	Start the components services. The exact steps depend on the system architecture and the deployed components, for example: `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-proxy-client-service.exe start` `C:\UDMG\UDMG Agent\agent\udmg-agent-proxy-server-service.exe start`

Installing and Configuring the Components

# UDMG Server Hostname or IP
hostname = "localhost"
# UDMG Server Port
port = 18080

Please refer to Authentication Methods for the LDAP and SSO authentication options.

UDMG Agent Proxy

Create a directory C:\UDMG\UDMG Agent
Install the binaries as udmg-agent-proxy-client.exe and udmg-agent-proxy-server.exe

Agent Proxy Server Configuration

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

# ssh-keygen -t rsa -q -N "" -f "C:\UDMG\UDMG Agent\agent_key"
# ssh-keygen -t rsa -q -N "" -f "C:\UDMG\UDMG Agent\client_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

[agent]
# Listen IP Address
hostname = "0.0.0.0"
# Listen Port
port = "2222"
# SSH Priv Key
ssh_key = "C:\UDMG\UDMG Agent\agent_key"
# SSH Public Key
ssh_key_pub = "C:\UDMG\UDMG Agent\agent_key.pub"

# Service User
username = "mft"
# Service Password
password = "61ee8b5601a84d5154387578466c8998848ba089"

The password key will be used for the client authentication.

Agent Proxy Client Configuration

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

[client]
# UDMG Agent Proxy Hostname or IP
hostname = "localhost"
# UDMG Agent Proxy Listen Port
port = "2222"

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

# Default TTL to Connection Retry
ttl="5s"

# UDMG Agent Client Admin API
[client.api]
# Listen Port
port="2280"

# UDMG Server
[gateway]
# UDMG Server Hostname or IP
hostname = "localhost"
# UDMG Server Port
port = "18080"
# UDMG Server Username/Password
username = "admin"
password = "admin_password"

The password key will be used for the client authentication.

Setup the Windows Services

The UDMG components can be installed as Windows service with the WinSw tool.
