Welcome. As you see it's time to start considering migrating from Now products if you ever plan on upgrading hardware or the operating system. smirk

In theory your plan should work. The purpose of TM is to go back in time.

Just make sure that before you do it that TM has backed up recently.

In worst case if anything goes awry you can restore the whole computer from the last point in time backup. It works like charm too.


You should be fine as long as you keep a copy of the most recent database, which would be available in TM, or you can copy it manually to be sure.
