Comment 6 for bug 159223

Nope, it's not applicable anymore. The new packages use a Database file with a different name (but in the same directory).

So you can run 2 versions side by side. Attempting a data migration is simply the cp command.

P.S. let me know if there are any other bugs I need to comment on. I saw this one by chance in the firestorm of launchpad bug mail.
