Downgrade ACS 5.8 to 5.4

[st92]

Hi All,

I have a query that if are upgrading from ACS 5.4 to ACS 5.8 then the path is 5.4 --> 5.6 --> 5.8 but if the upgradation fails at 5.8 then can we directly rollback to 5.4 or do we have to come to 5.6 first?

There is no way within ACS to downgrade / rollback.

If you want to prepare for doing so as a contingency you would have to make and verify a backup of the earlier release(s), then reimage the appliance (if it's hardware) to that earlier version and patch level using the ISO DVD and then finally restore your backup onto it.

If you are upgrading VM-based ACS then you can make a snapshot from ESXi and restore it. A snapshot is best done after stopping the application server.

You are going through two step upgrade, it is not possible to downgrade.

ACS 5.4 is End of Sale and End of Support

If it does not work, as an alternative you can export users/groups, network devices, network device groups to the new system.

That said, ACS 5.8 is End of Maintenance which means that there will be no patches or maintenance release to fix the defects.

Only support is available till 2022 if you have a valid service contract.

ISE is the next gen ACS. Please look at http://cs.co/acstoise for more details.
