Q. How to migrate from cyrus with an admin account?
Q. I'm migrating from WU to Cyrus, and the mail folders are under
/home/user/mail but the tool copies everything in /home/user, how
can i avoid that?
Q. I'm migrating from WU to Cyrus, and the mail folders are under
/home/user/mail directory. When imapsync creates the folders in
the new cyrus imap server, it makes a folder "mail" and below that
folder puts all the mail folders the user have in /home/user/mail,
i would like to have all those folders directly under INBOX.
Q. Migrating from Groupwise to Cyrus
Now the questions again with their answers.

Q. How to migrate from cyrus with an admin account?
R. Use:
imapsync ... \
--authuser1 admin_user ----password1 admin_user_password \
--user1 foo_user --ssl1
Instead of --ssl1 the alternative --tls1 can be used.
With --authuser1, the option --authmech1 PLAIN is set
automatically, you don't have to add it.
PLAIN authentication is the only way to go with --authuser1 for now.
So don't use --authmech1 SOMETHING with --authuser1 admin_user,
it will not work.
Same behavior with the --authuser2 option.
Do not forget the option --ssl1 or --tls1 since PLAIN auth is only
supported with ssl encryption most of the time. But it can
work without --ssl1 nor --tls1 if PLAIN is permitted in clear text
transmissions (the normal mode).
Add the AdminAccount to admins line in /etc/imapd.conf
Give AdminAccount lrswipkxtecda to the Cyrus Imap account
being migrated from, "joe" here.
Here is an example:
imapsync \
--host1 server1 \
--user1 joe \
--authuser1 AdminAccount \
--password1 AdminAccountPassword \
--ssl1 \
--host2 server2 \
--user2 joe \
--password2 joespassonserver2 \
--exclude "^user\."

Q. I'm migrating from WU to Cyrus, and the mail folders are under
/home/user/mail but the tool copies everything in /home/user, how
can i avoid that?
Two solutions:
R. Use
imapsync ... --include '^mail'
R. or (better)
imapsync ... --subscribed --subscribe

Q. I'm migrating from WU to Cyrus, and the mail folders are under
/home/user/mail directory. When imapsync creates the folders in
the new cyrus imap server, it makes a folder "mail" and below that
folder puts all the mail folders the user have in /home/user/mail,
i would like to have all those folders directly under INBOX.
R. Use
imapsync ... --regextrans2 's/^mail/INBOX/' --dry
look at the simulation and if all transformations seem
good then remove the --dry option.

Q. Migrating from Groupwise to Cyrus
R. By Jamie Neil:
I eventually managed to get the mail to migrate without errors using the
following options:
--maxage 3650
- some messages just don't seem to want to transfer and produce the
perl errors I mentioned before. This prevents the errors, but the
bad messages don't transfer.
Even though the mail migrated OK, there are a couple of gotchas with
Groupwise IMAP:
1) Some of the GW folders are not real folders and are not available
to IMAP, the main problem one being "Sent Items". I could find no way
of coping the contents of these folders. The nearest I got was to
create a "real" folder and copy/move the sent items into it, but
imapsync still didn't see the messages (I think because there is
something funny about the reported dates/sizes).
It think this problem has been rectified in GW6.5.
2) Version 6.0.1 of the Groupwise Internet Connector sucks. I was
getting server aborts when I pushed it a bit hard! I eventually had to
upgrade to 6.0.4 which seems to be a lot more stable.
