Cyrus.
As I had a REALLY hard time finding ANY help whatsoever ( scripts etc ), I
wrote some of my own.
I must say, they DO take time. I was running them on a Sun Fire 880 with
4x900MHz CPUs and 8GB RAM, and all files local. It takes around 8-10 hours
per 2500 users with around 20GB of data total.
So for 10000 users with around 80GB of data, up to 40 hours of conversion
time is a fairly close estimate.
I am sure that the scripts are not completely bug-free, but they did work
for me.
BEWARE: usernames with dots in them are NOT very well handled.
I converted 2300 users with 80G of mail over the course of 3 days, using a proxy solution. The accounts were moved over one at a time, with mail delivery held up and imap/pop login blocked while each account was moved. The proxies were a hacked perdition (to keep track of sessions so they could be killed and to treat a servername beginning with ! as a reject message to show to the client attempting to login) and a custom perl delivery agent which consulted the same database used by perdition and connected via LMTP (to procmail on the UW-IMAP side) to the two hosts. Based on the tests I had done (same V880 configuration on both old and new servers) it would have taken over 60 hours to convert everyone at once (using a hacked mboxcvt and a bunch of custom perl scripts), and that amount of downtime was unacceptable. That was also putting /var/imap on a tmpfs filesystem and striping /cyrus across 14 FC-connected drives.
