Order of installation during patch upgrade in Small ACS deployment

[iciar_acfe]

Hi

I am upgrading 2 ACS appliances from 4.1.4.13 to 4.1.4.13 patch 20. They are configured as primary and backup. In the documentation I don't see any restriction on which should be the first machine to be upgraded. Should the backup one be the first to be upgraded, and therefore, the "new" primary?

Thanks a lot.

Assuming all devices are pointing to the primary ACS IP, you should stop the replication, upgrade the backup, then upgrade the primary and then enable replication. Although I do not see any problem upgrading the primary first after replication has been stopped.

HTH,
