Hi all, I'm looking at upgrading our ACS 5.1 to 5.3. After reading the upgrade notes and seeing some of the issues experienced from the bundle upgrade I think I'm going with the fresh install / restore option. My only concern is that we're running a primary and secondary server in our environment; I have a plan to upgrade but wanted to run it by you fine folks to validate.
Here's my thoughts (please let me know if you see any potential pitfalls):
Backup the primary from the console
Promote the secondary to primary
Rebuild the "old" primary with 5.3 then restore the backup
Shut down the secondary server (now 5.1 primary) and rebuild that with 5.3
Once the secondary is running add it to the new 5.3 primary as a secondary.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
