Re: [Dovecot] Migration from courier to dovecot
Hey,
I am working on doing this migration myself. I have migrated some test
users. And I have build this script to help me, maybe you can use it for
inspiration(It is on your own risk to use it!):
#!/bin/sh
#Source="/var/vpopmail/"
Destination="/var/mail/vmail/"
i=0
for line in $(cat mailboxs.txt)
do
if [ -d $Source$line.maildir ]
then
# Create destination
echo "--Creating $Destination$line"
mkdir -p $Destination$line
# Load new data from backup
echo "--Copy from $Source$line to $Destination$line"
cp -a $Source$line.maildir $Destination$line
#If they exist mv trash, send and draft to .INBOX.
echo "--If exist then, mv trash send and draft to
.INBOX.XXX in $Destination$line"
if [ -d $Destination$line/.maildir/.Drafts ]; then
mv $Destination$line/.maildir/.Drafts
$Destination$line/.maildir/.INBOX.Drafts
fi
if [ -d $Destination$line/.maildir/.Trash ]; then
mv $Destination$line/.maildir/.Trash
$Destination$line/.maildir/.INBOX.Trash
fi
if [ -d $Destination$line/.maildir/.Sent ]; then
mv $Destination$line/.maildir/.Sent
$Destination$line/.maildir/.INBOX.Sent
fi
# Change the file right to the new system incl hidden files
echo "--Changes owner to vmail:vmail on
$Destination$line recursive"
chown -R vmail:vmail $Destination$line $Destination$line.*
# Run converter script if et reports an error we stop
the whole script
echo "--Calling courier-dovecot-migrate.pl"
/home/weiser/courier-dovecot-migrate.pl --to-dovecot
--convert $Destination$line.maildir
current=$?
if [ $current -ne "0" ]; then
echo "$current"
exit
fi
# move data from .maildir to ..
echo "--Moving data from ./.maildir to ."
mv $Destination$line.maildir/* $Destination$line
mv $Destination$line.maildir/.* $Destination$line
# remove old unused .maildir
echo "--Remove old courierfiles and folder and .maildir"
rmdir $Destination$line.maildir
/usr/bin/find $Destination$line -name
courierimapsubscribed -exec rm {} \;
/usr/bin/find $Destination$line -name courierimapuiddb
-exec rm {} \;
/usr/bin/find $Destination$line -name
courierpop3dsizelist -exec rm {} \;
/usr/bin/find $Destination$line -name courierimapacl
-exec rm {} \;
/usr/bin/find $Destination$line -name
courierimapkeywords -exec rm -f -R {} \;
i=$(( i + 1 ))
else
echo "$Source$line.maildir folder not found"
fi
done;
echo "$i mailbox mirgrated"
it needs to external files to work:
mailboxs.txt, which have a path to each mail folder:
domain1/user1/
domain1/user2/
domain2/user1/
and the courier-dovecot-migrate.pl which you can find more information
about here:
http://wiki2.dovecot.org/Migration/Courier
good luck.

Re: [Dovecot] migration from courier to dovecot
hmm, in the meantime i ran Courier on a new server and the situation is the same messages are downloaded again, I do not understand completely why the change machine ip is so important for email clients , or i miss smth :(
Re: [Dovecot] migration from courier to dovecot
domain is the same as was , only ip is changed ( new machine for mx ) the same config ( i dont want to users had to change smth ) i'm confused :((
Re: [Dovecot] migration from courier to dovecot
So the UIDLs are preserved perfectly. The problem is with something else then. Such as did you change the server address in the client's config? Some clients trigger a redownload because of that.

Problem is, the contents of cache files depends on what client is being
used. You could of course try to fetch the most commonly used fields
that clients use. Anyway, it's probably not a big deal. The worst that
can happen without index files is slightly higher load temporarily than
what it would have been under Courier.
With v2.0 you could do this pretty easily with doveadm command, but with
v1.x there's no super easy way to do it.

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 =) regards, Werner

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. =) -- David Halik System Administrator OIT-CSS Rutgers University dha...@jla.rutgers.edu

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 '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. -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.12 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktXgzgACgkQkPq5zKsAFijVzwCghnlpxhinrnAzGE702j3gfQ23 HRMAniY4fZ3f4bjKpwH1GllXyiTiCvbB =MpBR -END PGP SIGNATURE-
