merging two imap accounts

[nanooq at nanooq.org]

Hello to all,

the documentation of offlineimap and the FAQ are absolutely worth their 
name. Allow me to answer my own question to end this thread.

0.) Do backup.
1.) $ mkdir ~/archives
2.) $ mv ~/Maildir/IMAPnew/INBOX ~/archives
3.) $ mv ~/.offlineimap/Account-IMAPnew/LocalStatus/INBOX 
~/archives/LocalStatus-INBOX # [0, read the stuff about sqlite]
4.) $ mv ~/.offlineimap/Repository-IMAPnew/FolderValidity/INBOX 
~/archives/FolderValidity-INBOX
5.) Clean the cache $: rm -rf ~/.offlineimap/Account-IMAPnew # [1]
6.) Clean the Maildir $: rm -rf ~/Maildir/IMAPnew
7.) $: mkdir ~/Maildir/IMAPfinal
8.) $: offlineimap
9.) $: rsync --archive --verbose -P ~/Maildir/IMAPold/ 
~/Maildir/IMAPfinal/ # Pay attention to trailing /] this is a local 
merge.
10.) $: offlineimap # this syncs the local merge to the IMAPnew-remote 
server.

Lastly, I thank the community and developers for such a great programm 
und documentation.

Cheers,

nanooq
