We are on 14.1.3 now, when I upgrade DA can I install 14.2 and then 14.2.2 and then upgrade DBs directly to 14.2.2? or do I need to upgrade to 14.2, upgrade DBs, then upgrade to 14.2.2 and upgrade DBs again? Thanks
Always refer to the upgrade guide. It usually states to install 14.2, upgrade the databases, install 14.2.2 and upgrade the databases again.
You could also have a look at the versions of the ca / da database to see if the version has changed and go ahead accordingly (which I believe it always does).
