Thanks vkaryl. My problem is even more complicated -All I have is the db backup, and no current installation. If I understand you and the info on tamba2, then I’ll need to install 1.5, import the old (url corrected) database, then upgrade the whole site to 2.0. If this is correct, does it matter which version of 1.5 I use? I’m not certain how to determine which exact version the db came from.
