Upgrade from Etch to Lenny

[DecIRC]

I have a server running Debian Etch and ispCP 1.0.0 OMEGA build: 20090225.

I'd like to upgrade it.

I'd like to know if it's better to upgrade first ispCP or the OS.

For the OS upgrade, the following proposal is made

Code:

The following packages will be REMOVED:
  libcurl3-dev libcurl3-openssl-dev libgssapi2 libpci2 libperl5.8 libsasl2 libssp0 linux-kernel-headers proftpd-mysql
The following NEW packages will be installed:

380 upgraded, 65 newly installed, 9 to remove and 0 not upgraded.
Need to get 242MB of archives.
After unpacking 134MB of additional disk space will be used.
Do you want to continue [Y/n]?

I always have a stress regarding the package to remove... Is there a risk ?

Thanks for your advice...

Regards
Cedric

1. Make backups!!
2. Upgrade OS first, then ispcp
3. Be *extremely* careful when asked about what to do with new default configuration files (you should manually inspect the differences and add whatever new directives make sense instead of replacing old files with newer directly).
4. Don't forget this step from the update process (after having updated your system to lenny):

Code:

# aptitude update && aptitude safe-upgrade
# aptitude install lsb-release
# aptitude install $(cat ./docs/Debian/debian-packages-`lsb_release -cs`)

This will take care of any missing packages you may have after updating.
5. During the whole upgrade process your services will be down. I recently updated a heavily loaded system (+200 accounts, +1500 mailboxes) from etch/1.0.0 to lenny/1.0.6 and it took me near 4 hours. Assume that it will take some long time, warn your customers about the outage and stay calm, because trying to rush it will probably destroy your system.

Good luck!

Sure you know already, but remember to do the system upgrade by :

apt-get dist-upgrade

and not

apt-get upgrade
