We patch our servers monthly with OS patches.
We patch our servers with TES/CWA updates only as needed.
Needed means.....
- We are reaching end-of-life support (such as 5.3.1 last year)
- We want a new feature in an update
- We are experiencing a hardship bug that an update fixes.
Otherwise, system reliability is our #1 priority, so we don't change what is working. No CWA patching/upgrading. We may go years without upgrading if all is working great.
