Our QuickSilver G4/733 MHz is running Panther, Mail 1.3.11. This is where we take care of our POP mail with the ISP, cox.net. Occasionally, I want to transfer all mail folders to my iBook G4/1.33 GHz running Tiger, Mail 2.0.2, for a trip. On the iBook, an I simply remove the folder at: (home)>Library>Mail and then replace it with a copy of the folder from the QuickSilver at: (home)>Library>Mail ? Would the names of the "homes" need to be identical? Where the Tiger mail folder has extra items in it, would these be automaticaly regenerated when I start up Mail? These extra items are: Envelope Index MessageRules.plist MessageRules.plist.backup OpenedAttachments.plist Signatures (folder) SmartMailboxes.plist If the above would not work, should I just use File, Import Mailboxes in Tiger Mail? Then, I think I'd have to slowly rearrange the newly arrived folders to replace the old folders.
