[How to] Upgrade Plesk 8.1.1 on Debian 3.1 to Plesk 8.2 on Debian 4.0

[Daniel15]

This upgrade is actually quite simple
1) Download the Plesk 8.2 autoinstaller for Debian 3.1 from http://www.swsoft.com/en/download/plesk82/. Upgrade your current installation and make sure everything works fine
2) Edit your /etc/apt/sources.list file and change all "sarge" references to "etch". For example, this is what my file looks like:

deb [url]http://204.152.191.7/debian/[/url] etch main
deb-src [url]http://204.152.191.7/debian/[/url] etch main
deb [url]http://security.debian.org[/url] etch/updates main

deb [url]http://packages.dotdeb.org[/url] etch all

deb [url]http://autoinstall.plesk.com/debian/PSA_8.2.0[/url] etch all

Make sure the Plesk line says "PSA_8.2.0"
3) Update the package listing by running apt-get update
4) Perform the upgrade by running apt-get dist-upgrade

I've just done this, and haven't encountered any large problems so far. One minor problem is that /etc/crontab is overwritten by the Debian upgrade. After the upgrade, open your /etc/crontab file and change it to:

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command

Another minor problem was that this error popped up:

===> Preparing upgrade
 Trying to backup MySQL database... done
 MySQL databases are dumped to /var/lib/psa/dumps/mysql.preupgrade.dump.gz
/var/lib/dpkg/tmp.ci/preinst: line 4473: PREPARE_FUNCTIONS_82: command not found
It is problem with inet daemon

I'm not sure whether this is bad or not (I've got no idea what "PREPARE_FUNCTIONS_82" is actually meant to be )

Anyways, hope I helped someone . Like I said, I haven't encountered any major problems (my sites still work fine), but I'll try and post back here if I find anything.
