Hi All,
Just sanity checking this..
We have 2 x CPPM on 6.5.1 and want to upgrade them to 6.5.6. They are in a cluster with VIP & standby publisher configured. AAA and captive portals are pointing at CPPM VIP (wasn't me).
CPPM1: pub
CPPM2: sub (standby pub)
I want to upgrade with zero downtime.
This is how I plan to do it:
1. Disabled standby publisher (enable publisher failover false)
2. Upgrade CPPM1
3. VIP will failover and auth & captive portals will continue to work
5. Ensure CPPM1 is back up (event viewer shows upgrade complete)
6. VIP fails back (possibly?)
7. Upgrade CPPM2
8. VIP definately fails back to CPPM1 (if it didn't in step 6) Can someone clarify this?
9. Ensure CPPM2 is back up (event viewer shows upgrade complete)
10. Verify cluster sync is showing "ENABLED"
11. Enable standby publisher
12. Party time!
I know this is simplified in terms of what to do in each step but can someone verify that this should work as planned with zero downtime?
Cheers
James
