I couldn't spot anything on this in the upgrade instructions, and as it's something that could affect lots of people, I thought I'd ask the question here.
When upgrading CiviCRM, what is considered best practice regarding extensions? Should they be disabled prior to the upgrade?
If, as a result of upgrading Civi, one or more of my installed extensions is no longer compatible, what's the best procedure to follow? Should I attempt to update/upgrade extensions to a compatible version before or after upgrading CiviCRM?
