Hi.
I hat to rebuild a new server with fully new cyrus. Now i must bring the old messages to the new cyrus. Only copy get wrong.
What are the goals to do that? Wich files (mailboxes.db, cyrus.cache, cyrus.header, and so on) shout i bring it to the new system?
1. Dump your mailboxes-Database on the old system: ctl_mboxlist -d > mailboxes.dump Copy the resulting "mailboxes.dump" to the new server.
2. Copy the imap mail store 1:1 to the new server: example (here on both machines, the store is in /var/spool/imap, the target directory must exist and be writable by the cyrus user):
cd /var/spool/imap tar cvpf - . | ssh [EMAIL PROTECTED] "cd /var/spool/imap; tar xpf -"
3. Copy the following directories to the new system (do it like you have done with your mail store):
- Sieve (e.g. /var/imap/sieve) Databases: - Quotas (e.g. /var/imap/quota) - Seen/Subscribed (e.g. /var/imap/user)
Warning! This will work only if your new cyrus system uses the same database backends as the old one!
Losing the databases results in the following:
- Quotas: The user will not have any quota restriction anymore.
- Seen/Sub: The user will not see which messages are marked
"read" nor it will now which mailboxes he was subscribed to.4. Reconstruct a new mailboxes-Database on the new system: ctl_mboxlist -u < mailboxes.dump
5. Run reconstruct on the new system. reconstruct -f
6. When used quotas on the old system, run on the new one: quota -f
7. Tricky part: SASL user database
When sasldb was used, then:
If your new sasl lib uses the same database backend as the old one, you may simply copy
your old sasldb to the new server when these conditions are met:
- Your realm is the same as on the old server. - The database backend is the same
You may still set the same realm/imap server name as the old one in your imapd.conf.
If your IMAP realm is your hostname or your sasl database backend is another one, you
must use a program to dump the contents of the old sasldb. As passwords are stored in clear-
text it is not very difficult to accomplish that.
