[cisco-voip] UCCX 8.5.1sr3 to sr4 to Refresh Upgrade 10.5.1

[Heim, Dennis]

If you have the resources available (time and/or money), my preference is to migrate the environment to an offline environment.  If you have the compute resources do it there, or if not some type of Lab a Service (LaaS). Maybe use Veeam to migrate virtual machines, if you are already virtual (make sure to sure mac addresses to manual prior to copying).

Then you need to determine what you time frame is.. can you lose a few days of: cdr’s, historical reports, etc. Migrating VM’s between environment would need to be worked out. However, that allows you to identify any issues, develop a realistic timeframe for each aspect of the upgrade process. Most importantly, it allows a lot of the work to be done not in the middle of the night.

Wow.  Are you going MCS to UCS too?  If not, I'm doing that exact upgrade very soon and no documentation I have reviewed indicated how long upgrades would take, let alone 5 hours.  Right now my plan has a time budget of 3 hours for the same, which does not include moving ISOs to the datastore (I like doing local upgrades) nor upgrading clients.

Which portion is taking 5 hours?  Could you break it down by task for us?  E.g., L2 to SU4, Switch Version to SU4, RU COP, RU to 10.5, Switch Version to 10.5.

Did you disable IO Throttling first?

Based on my research here are the summary steps to this exact upgrade (sans client upgrades):

1. Upload ISOs to DataStore
2. Disable IO Throttle on Publisher
3. Mount 8.5(1)SU4 ISO
4. Upgrade Publisher to 8.5(1)SU4
5. Switch Version to 8.5(1)SU4
6. Patch Publisher with RU COP
7. Shutdown Publisher
8. Modify VM Settings: RAM from 4GB to 8GB
9. Power On Publisher
10. Mount 10.5(1)SU1 ISO
11. Upgrade Publisher to 10.5(1)SU1
12. Switch Version to 10.5(1)SU1

One UCCX node in ha pair 5 hours doing upgrades...it would be more enjoyable watching paint dry...there has got to be a better method in the future for L2 upgrades than this..
