There is a lot of documentation and discussion on this site, but I didn't see this question answered anywhere so I thought I'd ask. How do I upgrade to 7.2 while retaining the ability to roll back to 7.1 if something mission critical stops working with 7.2? The developers of several of my plugins appear to have stopped maintaining them, so this is a real concern for me.
I assume I want to back up the database. What else? It sounds like new Library directories get created by 7.2, so would a rollback be as simple as removing 7.2 and installing 7.1 again?
Thanks!
