Upgrade from Wheezy to jessie with ISPConfig3

hello,

i have now successful updated from squeeze to wheezy.
i must remove dovecot via autoremove.
ispconfig running without problem.

but if i do a upgrade from wheezy to jessie (the upgrade itself working fine),
i cant connect to the ispconfig port. now webhost are working (403 forbidden).

so now, how i can ispconfig back working? with all hosts?

and my other questions:
if i do the upgrade from squeeze to wheezy, what i should select for "new configuration files" php.ini eg, keep or replace?
what i should do after upgrade to get dovecot working again? must i reinstall all packages?

i have tested this wis a backup-test machine.

can anybody tell me, how i can do this upgrade correct?

thanks!

many greets

 

you must update ispconfig after a upgrading to jessie

 

i have tried this in shell:
ispconfig_update.sh

but no updates to install... or what you mean?
or do you mean the ispconfig install package updater?

what i should do with the removed packages from squeeze / wheezy?
and should i replace the old configuration files in update progress?

thanks

 

Code:

cd /tmp
wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
tar xfz ISPConfig-3-stable.tar.gz
cd ispconfig3_install/install
php -q update.php

and choose "reconfigure services" during the update. afterwards login into ispconfig and resync the websites (-> tools)

 

Thank you, and my last questions:

1. what i should do with the removed packages from squeeze / wheezy? must i reinstall any packages? or must i use the new installation lines from jessie setup (ISPConfig perfect setup?) before i execute the ISPConfig Update?
2. and should i replace the old configuration files in update progress (apt-get dist-upgrade)?

3. what you are using for upgrade? my update commands from squeese (are this correct?):
apt-get update
apt-get upgrade
apt-get dist-upgrade

# replacing all lines
/etc/apt/sources.list:
deb http://ftp.at.debian.org/debian/ wheezy main
deb-src http://ftp.at.debian.org/debian/ wheezy main
deb http://security.debian.org/ wheezy/updates main
deb-src http://security.debian.org/ wheezy/updates main
deb http://ftp.at.debian.org/debian/ wheezy-updates main
deb-src http://ftp.at.debian.org/debian/ wheezy-updates main

apt-get update
apt-get upgrade

then i get this messages:
# Errors were encountered while processing: dovecot-imapd...

# to solve:
apt-get autoremove
apt-get upgrade

# wheezy installed!

# upgrade from wheezy to jessie
sed -i 's/wheezy/jessie/g' /etc/apt/sources.list

# getting some errors, i solved this with: apt-get install -f
apt-get update
apt-get upgrade
apt-get dist-upgrade

thanks
