migration from courier-imapd to dovecot

[Odhiambo Washington]

Hiya Labourers,

Happy Labour Day!

I have been using courier-imapd and squirrelmail for quite some time
now. However, I'd like to try out dovecot (in production). According to
the migration docs, it looks rather simplistic, until you realize that
you have to migrate over 10k users, some of whom have created web
folders, and with different names (some even with spaces). I am writing
a simple shell script to accomplish the steps dovecot docs say are
reqd for change over, but I am not getting far as far as the display
of the folders on the squirrelmail web interface.

I know I have to do two things:

1. Copying of the files in ~/Maildir/ (see the script below)
2. I also need to do this for, I believe, the $user.prefs file in
   squirrelmail's data directory.

I am wondering if anyone in an ISP environment, having used SM and
courier-imapd, ever migrated to dovecot and if they are willing to
share the scripts they used in the process.
I am for sure still missing on something I need to do, because
when I make the changes, successfully hopefully, only default folders
are displayed.

Here is mine, which is still not clean, but which seems to do what
is said at:

http://wiki.dovecot.org/moin.cgi/Migration#head-06970f94fb8698efb2155667265adf3a834d15ea

It's simplistic, and perhaps needs perfecting: If an

#!/usr/local/bin/bash

# Script to create the necessary files in ~/Maildir for
# migrating from courier-imap to dovecot. 20050501

# store a user's home directory here for testing purposes
DIRNAME="/home/wash/Administration/IMAP/TESTDIR"
cd $DIRNAME

# In every directory in $TESTDIR, go in, find the files named
# courierimapsubscribed and courierimapuiddb and make the
# dovecot equiv.

for userdir in `ls -1`; do
        cd $userdir/Maildir
        for dir in `find . -type d \! -name "." -name ".*"`; do
		cd $dir
                if [ -f courierimapsubscribed ]; then
		cp courierimapsubscribed .subscriptions
		if [ -f .subscriptions ] ; then
		sed -i.bak -e "s/INBOX.//g" .subscriptions
		if [ -f courierimapuiddb ]; then
		cp courierimapuiddb dovecot-uidlist
		fi
		fi
		fi
		rm -f .subscriptions.bak
        done
done
#


This appears to do what I want, at least, but ....
