Hi

I did

1. create new mailboxes on target server and added quotas

2. The below
XXX.YYY.COM:/home # more /tmp/migrate-imap.sh 
./imapsync  --host1 192.168.3.5 --user1 per --passfile1 /root/passfile-per --authmech1 plain --host2 XXX.YYY.COM --user
2 per --passfile2 /root/passfile-per --authmech2 plain --delete2  --expunge2 --syncinternaldates --subscribe --syncacls --ex
clude 'Other Users.*' --exclude 'Shared Folders.*'
./imapsync  --host1 192.168.3.5 --user1 john --passfile1 /root/passfile-john --authmech1 plain --host2 XXX.YYY.COM --user2 john 
--passfile2 /root/passfile-john --authmech2 plain --delete2  --expunge2 --syncinternaldates --subscribe --syncacls --exclude 'Other
 Users.*' --exclude 'Shared Folders.*'
---cut the rest----


It's resonalbe fast

The bad thing is that you need all passwords.

So this is not an ideal solution, but for sure it works great when you don't have all the time you would like to dig for a better solution. I did this for only 20-30 persons and could therefor live with the password issue. A few of them had mailboxes of 3-6 GB each. 

Hope it could be of any help
