Moving Alternate Storage to another disk.

[Urban Loesch]

Hi,

if you have the new disk installed on the same server you can try:

- mount new disk for example in /mnt/temp
- rsync -vaWH all files + directories from the old to the new disk
- stop dovecot so no changes will happen on disks
- make a final rsync again -> should not take many time
- umout the old disk
- mount new disk to the original "alt-storage" path, so you don't have to change each soft-link in each users directory.
- start dovecot

Not tested, but in theory it should work.

Best
Urban
