UPgrade ACS 3.2 to 3.3 then to 4.1 Configuration Preservation

[dvaggalis]

If I upgrade from 3.2 to 3.3 then to 4.1, will I retain my original configuration from 3.2 or will I need to start over. will the database be preserved as well?

yes you will have all the configuration, you wont be required to rebuild it from scratch.

During upgrade, as per upgrade path, make sure that you choose to keep the configuration from previous version. It is check box, if you miss it, it will remove all the previous configuration.

But in any case, keep a database backup from version 3.2.

Are there any gotchas in updating ACS from 3.2(3) to 4.1, via 3.3(3)?

In particular, I noticed in the ADU docs that ACS 3.x EAP-FAST PACs are not compatible with 4.x PACs. However, if auto-provisioning is enabled, client should just need to accept a new PAC?
