Inplace upgrade CentOS 6 to 7 /w Plesk 12

[RobHost]

As of Plesk 12.1 the dist-upgrade from Debian 6 to Debian 7 and also from 7 to 8 is supported, what about CentOS?

Is migration from CentOS 6 to 7 supported or will it be supported in any upcoming version before CentOS 6 reaches EOL?

See http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool

Thanks!

We do not support distupgrade for CentOS http://download1.parallels.com/Ples....0-for-linux-installation-upgrade-info.html#1

Plesk does not support major OS upgrade (dist-upgrade).

I talked about 12.1 - and there dist-upgrade for Debian seems to be supported regarding your documentation: http://download1.parallels.com/Plesk/PP12/parallels-plesk-12.1-for-linux-change-log.html. What about CentOS then?

The same story for 12.5 - http://download1.parallels.com/Ples....1-for-linux-installation-upgrade-info.html#1

Debian 8 and dist-upgrade from Debian 7 to Debian 8 are supported.

 

[IgorG]

Yes, distupgrade supported for Debian but not for CentOS.

Thanks. And will it be in any upcoming release?

 

[IgorG]

I think no. There are a lot of serious and complex internal differences between CentOS6 and CentOS7.

What do you mean?
What especially? Debian 8 also uses systemd. Thanks.

CentOS6 to CentOS7 distupgrade is not stable even without Plesk. It doesn't work as expected. We did many tests without Plesk and it doesn't work. We can't give unstable solution for our customers. Debian 8 has SystemVinit and systemd and you can perform distupgrade from SystemVinit to SystemVinit and then switch to systemd or not switch. But CentOS7 has only systemd and distupgrade from SystemVinit to systemd is real pain.

Because of this i'm planning to start a clean install and move all the data to the new VPS.

Which Linux disto is preferred or best supported for Odin?

CentOS or Debian

 

[rgruyters]

Ok. But in case of CentOS you advise to do a clean install when you want to upgrade to CentOS 7?

 

[IgorG]

You can install Plesk to CentOS7 - http://download1.parallels.com/Plesk/PP12/plesk-12.5-for-linux-installation-upgrade-info.html#1

 

[rgruyters]

I know, but this thread is about dist-upgrade from CentOS 6 to CentOS 7 and Odin advise against to do a dist-upgrade. (or at least that is how I'm reading it)

 

[IgorG]

As I wrote before we do not support distupgrade for CentOS.

The real problem is that updating with a new clean install then we can no longer install the Customer & Business Manager ...

 

[IgorG]

CBM is legacy product. We do not plan on developing and introducing major changes to Customer & Business Manager at the moment.

 

[Pino]

I know, but to me it is all right now and I have a license, so I can not update or lose everything. This is bad.
