Pre-Installation / Upgrade Backups

The installation process overwrites the current files (exception: the configuration files are kept), effectively removing your modifications. Backing up these files will optimize the time it takes you to get up and running after installing or upgrading.


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.


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 installation packages, binaries, services, and environment variables have changed and this does not allow for a standard upgrade.

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.
