Import address book from previous version

[grpprod]

Hi,
is it possible to import all users' address books from older RC version to latest? I would like to do this automatically and not ask my users to manual export/import a vcf.

If it is possible, I would appreciate a way to import all other user preferences, eg Identity name, signature etc.
thanks

You can upgrade the old RoundCube database to the current version, see http://trac.roundcube.net/wiki/Howto_Upgrade

Thank you for this. I did it with no issues.
