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.
[Dovecot] Migration from Courier to Dovecot: is it recommended to "force" d.index* creation?
Hello,
we are planning to migrate from Courier to Dovecot.
We already know courier-dovecot-migrate.pl, that will convert UID list
and subscriptions files to dovecot format, and we will run it in batch
on all Maildir + enable it at login, once we do the switch
But we are also wondering it it might be wise to "force" the creation of
dovecot.index{,.cache} files at conversion-time. It seems that, at
least, d.i.c is created at FETCH of a mail, i.e. reading it, but we do
not want to "alter" mails status of our clients.
Is there a way to create them in batch, or is it better to just let them
be created once clients start accessing their mailboxes via dovecot?
Thanks in advance,
Sandro

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

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`.

[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 [1] http://www.dovecot.org/tools/courier-dovecot-migrate.pl
