Upgrade from ACS 5.4 patch 6 to ACS 5.5 patch 4 advice
I have a pair of ACS 5.4 patch 6 running on VMWare as primary/secondary with Active Directory integration working without any issues.
I would like to upgrade them to ACS 5.5 patch 4. Here is my plan:
1- De-register the Secondary ACS 5.4 patch 6 2- shutdow the de-register Secondary ACS 5.4 patch 6 2- Take a backup of the Stand-alone Primary ACS 5.4 patch 6 3- shutdown the Primary ACS 5.4 patch 6,
4- build a brand new ACS 5.5 with the same name and IP address as the previous Primary ACS 5.4 patch 6 5- patch the ACS 5.5 with patch 4, 6- perform a restore of the old ACS 5.4 patch 6 backup on the Primary ACS 5.5 patch 4, 7- Re-join the ACS 5.5 patch 4 with Active Directory, 8- build a brand new ACS 5.5 to be with the same name and IP address as the previous Secondary ACS 5.4 patch 6 9- patch the new Secondary ACS 5.5 to be with patch 4, 10- join the new Secondary ACS 5.5 patch 4 with Active Directory, 11- join the new ACS 5.5 patch 4 in step 4 as the Secondary ACS,
Anyone see any issues with this? I used the same steps when I upgrade from ACS 5.2 patch 3 to ACS 5.4 patch 6
Yes your plan will work. Why don't you leave the primary up until you get the secondary back fully operational with 5.5 patch 4 with the database restored? You would want to make sure your backup restored properly before wiping the primary.
Why wouldn't you do an upgrade? Just install the upgrade patch that Cisco put out. I upgraded 3 ACS servers and had no problems.
I completely understand. From page 11-14 of the Installation and Upgrade Guide for 5.5
"While restoring the data, using the 5.4 backup file, this command restores the ACS 5.4 configuration data. It also converts and upgrades the ACS 5.4 Monitoring and Report Viewer data to the 5.5 format."
It should work. Also, if you don't want to actually shut the ACS down you could just shut the switchport down. Might be a little quicker if you find that it's not working and you need to get it back up quickly. I guess that depends on how you deployed them though (appliance/VM).
