This document will highlight some key aspects of the upgrade process of the current Opmantek Applications.
To be able to upgrade you need to have the following version installed on your system.
|NMIS 9||9.1.0G or earlier version|
|opCharts 4||4.1.3 or earlier version|
|opConfig 4||4.1.1 or earlier version|
|opEvents 3||3.1.0 or earlier version|
|opHA 3||3.1.2 or earlier version|
|opReports 4||4.1.1 or earlier version|
As always, we strongly recommend to keep a backup of the current installation. This is a recommended practice and it's an important step on any software installation or upgrade.
The installer saves a log of all actions taken, files copied etc. in the installation directory as
install.log, ie. normally it'll be in
/usr/local/omk/install.log. Subsequent upgrades or installations of other Opmantek products will add to that logfile, so you may very well want to remove or clear the install.log file before upgrading or adding extra software.
Unless this is the very first installation of an Opmantek product on this system, the installer will offer taking a backup of all affected files before the installation commences. This backup will be saved in the
root user's home directory as omk-backup-YYYY-MM-DD.tgz. The backup includes:
How to restore from a failed upgrade
All opModule installers create a backup of /usr/local/omk prior to the installer running PROVIDED you answered the following question early in the installation procedure in the affirmative:
This is the process to use if you need to roll back from the installer using this backup:
Ref: Restore Backup after Install
You also need to run the installer for each previously application that was installed in order to downgrade properly and have the initd and systemd services restored too.
A couple things to remember -
There is no need to request a license update, as the licenses are continuing to be valid with this upgrade.
