Default Squeeze is in the pipe

This will be a great day for all Debian admins today, as squeeze is in the pipe to get ready for release today. Currently all CD/DVD images are being build. So can anyone provide information, if the migration from 5.0.8 and newest ISPConfig to squeeze will work like a charm or are there some known blockers?

My setup is currently based on Courier as i fear a Dovecot migration currently, but maybe someone can provide information about this topic as well, so i will do a two-step-migration tonight.

Thanks in advance and be prepared for upgrading :-)

Brgds,

Timo

What should i say? Migration to squeeze worked like a charm. I changed my apt sources like this:
Code:
# Strato Debian mirror
deb     ftp://ftp.serverkompetenz.net/debian squeeze main contrib non-free
deb-src ftp://ftp.serverkompetenz.net/debian squeeze main contrib non-free

# Security updates
deb     http://security.debian.org/ squeeze/updates main contrib non-free

# volatile packages like clamd
deb     http://mirrors.kernel.org/debian squeeze-updates main contrib
deb-src http://mirrors.kernel.org/debian squeeze-updates main contrib

# up2date PHP and MySQL versions for stable Debian tree
deb 	http://packages.dotdeb.org squeeze all
deb-src http://packages.dotdeb.org squeeze all
then did the magic trick:

Code:
aptitude clean; aptitude update; aptitude install linux-image-2.6-amd64; aptitude install udev
installing newest kernel and udev versions is suggested in squeeze release notes. After that i did a reboot.

Code:
aptitude dist-upgrade
installed all updated packages. I did another reboot after this.

Code:
upgrade-from-grub-legacy
installed grub2 into the MBR and i was done. A last reboot was necessary to check, if grub2 boots well and then i opened the bottle of beer i already prepared :-)

Just one thing is left and this is the migration from Courier to Dovecot :-(

Courier is still available, but i'd like to use Dovecot.

One lil bug i discovered yet. Some, not all, mailboxes were not available via POP3 and IMAP. After disabling POP3/IMAP access in ISPConfig, waiting a bit, an re-enabling it, all logons were successful. I was not able to discover what the problem was exactly.

@gebelmeyer

Courier and dovecot use different mailbox layouts, so you can not switch a ispconfig 3 mon. courier install to dovecot by simply replacing the lda and pop3 / imap daemon. So what you named a bug is simply a incompatible layout and not a bug. Switching from courier to dovecot without adjusting the mailbox layouts manually will cause a loss of imap emails, additionally you will get login problems as you mentioned above and all email filetr rules will fail.

I recommend to not change the pop3 / imap daemon on system update if you dont want to loose emails. There is no technical need to change the imap and pop3 software on update.

Hey till,

this is what i expected and that is why i DIDN'T changed from courier to dovecot. These login-problems exist since i upgraded my machine from lenny to squeeze. I fixed them all, but other users should be aware of this.
