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:
- Do you want to perform a backup of your installation directory?
- Default answer for automated install is 'Yes'.
This is the process to use if you need to roll back from the installer using this backup:
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 -
- Each run of an opModule installer creates a new backup file. However, since they all use the same name only the most recent will be maintained. If you are installing several packages you should rename each backup before running the next.
- This process overlays the backup into the /usr/local/omk directory and DOES NOT replace it.
