When upgrading to RSA Authentication Manager 8.x, or from a lower version of 8.x to a more recent version, there is an order for installing versions, service packs and patches. This article explains the upgrade order.
The upgrade order for RSA Authentication Manager is as follows:
Authentication Manager 8.0
Authentication Manager 8.1
Authentication Manager 8.1 SP1
Authentication Manager 8.2
Authentication Manager 8.2 SP1
Authentication Manager 8.3
Authentication Manager 8.4
If, for example, you are currently running 8.2 SP1 and want to upgrade to 8.4, you must first upgrade to 8.3. Once you are on 8.3, you can then proceed to install 8.4.
When upgrading from one minor version to another (8.3 to 8.4, for example), you do not need to install any released patches or hot fixes, for that version unless expressly mentioned in the release notes.
As of this writing (20 February 2019) patches have not yet been released for 8.4. Once they are released, please be sure to install them on your primary first then on all replicas.
