Re: FAQ How to change a userid
This sounds appealing, do you know if it handle seen state and subscriptions properly? (Since UW does not support sieve, you would probably have to do sieve manually, but that shouldn't be too bad.) How about specifying the partition? I wasn't incredible pleased with our script because it is directly manipulating the file system, but we were trying to come up with something that would be complete.

If anyone is interested, we have a perl script that does the following: The script will: #1) obtain list of mailboxes under the old UI via direct IMAP calls #2) create the new mailboxes via direct IMAP calls #3) do the recursive copy of mail files from old UID to new UID #4) reconstruct new UID mailbox #5) get the seen file for the old UID and prep for the new UID #6) get the contents of all cyrus.header files for old & new UIDs into arrays #7) hula-hoop thru seen file stuff; do tricky search and replace #9) handle search and replace for old UID to new UID in .sub file #10) move any sieve scripts to the new UID I can't say it is a perfect implementation because it does not try to address items 2 or 3 below, but these are not used extensively in our environment.
