The latest version of Zimbra doesn't recognize the last version installation. When I go to install it, the only thing it asks is if I want to install in the same folder, not upgrade. If I do that, it does not work. If I do a new install, Zimbra works fine. I have my old installation backed up. Can I copy the files and mail over to the new installation folder and what files or folders would they be? I have a calendar, 5 email accounts, and a gig of mail I don't want to lose and would hate to start from scratch.
