I did the Upgrade from Application manager. Everything went smoth it seemed.
I like the new version so far.

One thing I noticed.
For the map repositories that I had downloaded mapd for already - when I used those, I saw a message about a legacy maps and it created a file like GSat.db
For a map repository that had not been used before, but had the repository set up - just no maps. I didn't see the legacy message (OK) but the file it created was called just VEStreet
The file I expected to be named VEStreet.db
(no big deal I just expected the .db extension.
