Yes although its been slightly customized for our environment and its a bit of a hack. I see John Lightsey version is way better than ours and that you have improved upon it.

Re: [Dovecot] Courier->dovecot migration script
W is the size of the file with CR/LF for newlines. It's the same size courier stores in the POP3 uildlist file. I wrote an updated version of the courier-dovecot migration script that attempts to convert in both directions (using the V3 dovecot- uidlist format) a while back. It's freely licensed if you want to give it a try. http://httpupdate.cpanel.net/cpanelsync/EDGE/bin/maildir-migrate On Nov 12, 2008, at 11:59 PM, Paul Gamble - MWEB wrote: Hi Timo I aplogise if this is documented somewhere (couldn't find it), but could you tell me what the "W" field represents in a v3 dovecot-uidlist file?

The migration script generates the files using uidlist format "Version 1". While Dovecot 1.1.x normally uses "Version 3" format, it can also read the older formats (to maintain backward compability), and thus auto-convert it to the newest version. FWIW, we have used version 1.1.7 of the script for our Couier to Dovecot 1.1.x migration, and it worked well, execpt for cases where Couier's uidlist was too old. Ulrich
[Dovecot] Courier->dovecot migration script
HI All, We have the latest Dovecot 1.1.6 running and I need to migrate some POP3 users over from Courier to Dovecot and would need to convert the courierpop3dsizelist to maintain the UIDs. I just need to confirm that the script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) only works for Dovecot v1.0 and not for v1.1? As the dovecout-uidlist file that is created (by the script) is not in the same format as dovecot-uidlist file that is created by the 1.1.6 server. Thanks, Warren
