imap migrate

[Jan Müller-2]

I'm having problems copying messages form the old server to the new
one. What is the best way to copy messages? It's couple of gigabytes.

I tried copying maildirs via scp, but it did not work. I found
imapsync  [http://freshmeat.net/projects/imapsync/] which should copy
messages from one server to the other. I have following problem:

+ NO msg #5145 [+XOMBo6zAwJfc4iQ1zztzg:3678] in INBOX
+ Copying msg #5145:3678 to folder INBOX
flags from : [\Seen][]
Couldn't append msg #5145 (Subject:[Autopos]) to folder INBOX: Error
sending command '8 APPEND INBOX (\Seen) "" {3678}
': 8 NO Error in IMAP command received by server.

This happends with every message, the script does not even create the
proper folders.

I just need to copy the messages, do you have any better ideas for migration?
The old server is on courier-imap + postfiix, the new server is courier based.

Thank you!

What scp command did you use?

How do you classify "did not work", what were the resulting symptoms
after you SCP'd.

The maildirs are highly portable in this sense, and should just copy
from one courier installation to another unless of course your SCP
command is leaving hidden file content behind, or there is a file /
folder ownership issue on the new side.

Regards,

Owen.

rsync should work just fine, make sure that ownership/permissions are
matching. Use rsync -a then.

For that kind of job I recommend (and use) rsync. You can do more than
one rsync job and keep the downtime between turning off the old server
and turning on the new server very short.

This is a bug in the script. "" is not a valid datetime stamp. This
parameter is defined as optional, which means it can be omitted completely.
But if specified, it must be a syntactically valid datetime stamp, and an
empty string isn't noe.
