[Dovecot] Migration from Courier to dovecot
hi list,
I've just registered to the list, so please be tolerant ;) I'm currently in the process of planning the migration from courier to dovecot as POP/IMAP-Server. I'm migration from Courier 0.58 (Debian-Etch-packages) to Dovecot 1.1.13 (Debian Lenny Backport).
The conversion of the Mailbox from Courier to Dovecot will be done with "courier-dovecot-migrate.pl"-script[1], which works fine. However after running "courier-dovecot-migrate.pl" the Courier-Files still remain in the Maildir.
Can i just delete those Courier-specific-files or does dovecot need them somehow (do you normally get rid of these after conversion)?
It's about these files: courierimapacl courierimapsubscribed courierimapuiddb courierpop3dsizelist
And those directories: courierimaphieracl courierimaphieracl
Can i simply delete those with "find" ? Furthermore: is it possible to convert back from Dovecot-Format to Courier-Format?
Thanks in advance, Werner

expressed unlucky :-)
sure, dovecot doesn't need these files after the migration. I have to test, if it's possible to convert from a previously "courier to dovecot migrated maildir" back to courier-format.

Some version of the script can do dovecot -> courier migration, without the courier* files, but perhaps unsurprisingly I've never been interested in writing or testing that code, so in the recent versions that I've modified it's probably broken.

I just wanted to chime in that we're going to rewriting part of the script to handle --location= at some point if anyone is interested. The script works great, but it doesn't have the ability to point to an area outside of the users' homedir for the conversion. If you're moving your users' index/uid/subscriptions to a non-quota area outside their homedir then this is necessary.
Unfortunately, that was something we learned too late after we did our migration. =)

Thanks for the info. I've asked because the convert-script offers the "--to-courier"-option, I've tried that and it didn't work for me =)

I 'migrated' a few years back from Courier to Dovecot without a script.
A few weeks ago I noticed those same files, and removed them with
find. I haven't noticed any degradation whatsoever :P.
