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

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, 1.2.x) to UDMG 2.0.x.

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.

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.

It may be required to modify the work and data directories ownership or access rights and to update UDMG Server transfer rules to use paths that are accessible by the 'udmg' user.

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

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

The installation process overwrites the current files (exception: the configuration files are kept), this may affect your modifications.

Backing up the configuration files optimizes the time it takes you to get up and running after installing or upgrading.

/opt/udmg/etc/udmg/nginx/udmg.conf
/opt/udmg/etc/udmg/agent/client.toml
/opt/udmg/etc/udmg/agent/server.toml
/opt/udmg/etc/udmg/auth-proxy/config.toml
/opt/udmg/etc/udmg/web-transfer/config.toml
/opt/udmg/etc/udmg-server/server.ini

After upgrading RPM or DEB packages, review the new configuration file templates (with the extension .rpmnew or .dpk-new) and edit the current configuration files to add new parameters or remove deprecated parameters.

...

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.

$ /opt/udmg/bin/udmg-server migrate --help
Usage:
  udmg-server [OPTIONS] migrate [migrate-OPTIONS] [version]

Help Options:
  -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 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:

$ /opt/udmg/bin/udmg-server migrate -c /opt/udmg/etc/udmg-server/server.ini --list | tail -n 2
1.5.0 [DATABASE]
2.0.0 [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.

$ /opt/udmg/bin/udmg-server migrate -c /opt/udmg/etc/udmg-server/server.ini -vvv
[INFO ] Migration: Starting upgrade migration...
[INFO ] Migration: Applying migration 'Bump database version to 2.0.0'

After the migration, the services for UDMG components can be started.

Upgrading Universal Data Mover Gateway for Linux

Upgrading with Linux Software Packages

...

Step 1

...

Contact your Stonebranch representative or Customer Support to receive the software package for the intended operating system.

...

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:

sudo systemctl stop nginx
sudo systemctl stop udmg-server
sudo systemctl stop udmg-auth-proxy
sudo systemctl stop udmg-agent-client
sudo systemctl stop udmg-agent-server

...

Step 4

...

Upgrade the UDMG packages (RPM or DEB), for example:

sudo rpm -Uvh udmg-agent-2.0.0.0.build.7.x86_64.rpm
sudo rpm -Uvh udmg-admin-ui-2.0.0.0.build.4.x86_64.rpm
sudo rpm -Uvh udmg-admin-ui-nginx-2.0.0.0.build.4.x86_64.rpm
sudo rpm -Uvh udmg-auth-proxy-2.0.0.0.build.15.x86_64.rpm
sudo rpm -Uvh --force udmg-server-2.0.0.build.3.x86_64.rpm

...

Review the component configuration files.
Refer to each component installation section below for the list of parameters.
/opt/udmg/etc/udmg/nginx/udmg.conf
/opt/udmg/etc/udmg/agent/client.toml
/opt/udmg/etc/udmg/agent/server.toml
/opt/udmg/etc/udmg/auth-proxy/config.toml
/opt/udmg/etc/udmg-server/server.ini

Note that new configuration file templates (with the extension .rpmnew or .dpk-new) that contain all the allowed parameters are added during the software package upgrade.

...

Review the component service configuration files.

For instance, the UDMG Authentication Proxy service file (/etc/systemd/system/udmg-auth-proxy.service) was installed with these parameters in version 1.5

[Unit]

Performing a manual installation

UDMG Admin UI

• Extract the distribution files for UDMG Admin UI, under the directory that was configured as web server root directory during the NGINX Server configuration, The standard value is/opt/udmg/var/www/udmg.

• The zip file can now be deleted.
• If SELinux is enabled on the host, proceed with the steps in the section below: Using UDMG with SELinux  
• Validate that the service is working properly, for example with the 'curl' command:

or with the browser: 

Image Removed

UDMG User Setup

• Create a dedicated user for running the UDMG modules and to be the owner of the files that are transferred by UDMG.

UDMG Server

• Create the configuration file /opt/udmg/etc/udmg-server/server.ini with the following parameters:

Using UDMG with SELinux

Security-Enhanced Linux (SELinux) is enabled by default on modern RHEL and CentOS servers. Each operating system object (process, file descriptor, file, etc.) is labeled with an SELinux context that defines the permissions and operations the object can perform. In RHEL 6.6/CentOS 6.6 and later, NGINX is labeled with the httpd_t context.

When SELinux is enabled, the UDMG Admin UI shows "403 access denied" and "404 page not found" errors on the landing page, and permission errors are reported in the NGINX log files:
