Migration from Plesk 8.1 to 9.5: safest way?

Hi,

I'm using a Virtuozzo PowerPanel and Plesk 8.1 based webserver running Debian Linux.
I want to migrate to a new Server with Debian and Plesk 9.5.

I have 20 Domains and accounts with PHP and MySQL based Web apps and email accounts running on the server, all administrated using Plesk.
I want to preserve all email and web and account configurations including passwords etc.

However, there is an error when I want to use the integrated Plesk Updater to update to 9.5 saying
"Not found source for system packages (release 3.1, codename sarge) in APT software sources configuration".


Now my question is: what is the safest (not necessarily the fastest) way to migrate to Plesk 9.5:

I can replace the virtual Server and install Plesk 9.5.
Or I can choose to get a new virtual server with a new IP while the old server is still available for migration.

What method would you propose?
I read in the Plesk 9.5 Migration Guide that I can do a backup on the source server, convert it and restore it on Plesk 9.5.
Can the configuration then be changed to the new IP automatically regarding all domains etc?

Thanks for your help.
 
I think that migration domains from old 8.x server to new 9.x would be best solution.
 
That would mean that I need 2 servers running at the same time to migrate using migration manager with a direct access to the source server?
And migration manager will configure all domains to the new IP adress automatically?
 
Is there a possibility to avoid the direct access to the source server, could I export the data for the migration wizard, too?
 
You can use backup/restore migartion method but I strongly do not recommend it. Migration or Plesk upgrade procedure much more safely. I would suggest you create full backup of your current server and perform upgrade procedure.
 
What do you mean with plesk upgrade migration? The "Plesk updater"?
I would prefer Plesk Updater, however my hoster told me, that the error above prevents me from using it.

Any idea how to fix it?
 
It looks like problem in that your sources list has specified packages from stable repository. But Debian 3.1 is no more in stable repository, currently stable repository - is Debian 4.0 or 5.0 version, 3.1 version was moved to sarge repository.
Therefore try to correct your source list. After that you will be able to upgrade Plesk. But do not forget to create fresh backup of your server just in case.
 
Thanks for you advice. Do you have some information about the file where the source url is stored and which new source url to use in my case?
 
And what is the correct source url I should use?

Furthermore: the updater will update my whole server with all new versions of the underlying software (apache etc.) does it?
 
Sorry, thats the whole content of source.list:

I'm sorry, but I dont understand:

Can I modify source.list in order to use Plesk Updater to update to Plesk 9.5? And the whole system services (Apache etc.) are updated, too?

If its possible, which source urls do I have to use exactly?
 
No, it will not upgrade anything except packages list.
Read apt-get Debian package utility documentation for details.
