Restore and / or transfer mail (boxes)

[nlrela]

Previously (until Yosemite) it was possible to copy / transfer mailboxes to another Mac or restore it
after a clean install by just copying the Mail folder to the Library directory.

With El Capitan it seems that there has been changed something and now it ain’t possible that easy
anymore. By just copying the folder back emails won’t appear in the Mail App anymore.

Is there already a proper way known for backing up / transferring email boxes to another Mac (which
other files do have to be copied / transferred as well)?

Thanks for your feedback.

Previously, Mail stored your data in Mail > V2. El Capitan, Mail is stored in V3. Normally, when you upgrade to El Capitan it imports the data from your V2 folder. Try File > Import > Apple Mailboxes > navigate to your V2 folder.

Not sure if this will get all the accounts or just the mailboxes.

I wrote Mail folder in the library as both V2 and V3 are there located. Till Yosemite it was enough just to copy (back) the V2 folder, by now copying V2/V3 is not sufficient anymore. Mailbox configuration has apparently moved to somewhere else as mails won't appear in the mail app by just doing so
