It is typically recommended to have a backup of the Progress / OpenEdge installation prior to application of a service pack or hotfix in case it is necessary to revert to the state before the SP or Hotfix was applied.
If a copy is made well in advance, the service pack or hotfix can be applied to the copy without disturbing the running processes.
This saves downtime as all the preparation can be made before the outage is necessary.
- Make a copy of the production installation directory.
- Apply the service pack to the copy of the Progress / OpenEdge installation.
- Apply any necessary owner, group, or permissions changes necessary with a hotfix.
- Wait till the planned downtime.
- Shut down all processes related to the production installation.
- When all processes related to the production installation are shutdown, rename the existing installation directory to something such as version-pre-sp or version-pre-hotfix.
- Then rename the copy of the installation where the service pack or hotfix was applied to the normal production installation directory name.
- Start up the production environment as normal.
