Server transfer: Ubuntu 12 to Ubuntu 14

[vtual]

Good day all,

I am trying to transfer Plesk 12.0.18#34 from an Ubuntu 12 server to an Ubuntu 14 server.

Using the transfer manager, I got these warnings:

The following Apache modules are not installed on the destination server: authz_default. Please install and enable these modules to prevent possible problems.
The following Apache modules are disabled on the destination server: proxy_http,proxy_html,proxy,authz_groupfile,reqtimeout. Please enable these modules to prevent possible problems.
The php_version 5.3 is not available on the destination server. Instead, Plesk will use the following version: 5.5. To use the same php_version as on the source server, you should turn on or install it on the destination server. 3 domain(s) will be affected.​

I am a bit puzzled by the authz_default warning as it is not supported anymore on Apache 2.4.

If I override and launch the transfer, I get these errors:

PHP Notice: Trying to get property of non-object; File: /opt/psa/admin/plib/backup/Conflicts/PleskDataManager.php, Line: 173

PHP Fatal error: Call to a member function capability() on a non-object in /opt/psa/admin/plib/backup/Conflicts/Resolver/UnfitSettingsResolver.php on line 292​

Would someone have a pointer to how I can solve these issues?

Thanks!

Looks like that IP mapping has worked incorrectly during migration. The reasons are difficult to understand without detailed investigation directly on servers.
I can only recommend to create a request to support team to do in-depth investigation to find the reason and to fix it. Please create a ticket to support at https://odin.com/hcap/support/request/ .
You may have free support, please check what kind of Plesk license you use for available support options at http://kb.odin.com/en/121580 .
If there’s no free support in your case, you can order Plesk per-incident support at http://odin.com/hcap/support/buy-support/. Support team will contact you as soon as purchase is processed, and they will do the best to resolve it.
If it is found that your problem was caused by product bug w/o available solution or workaround from Parallels, then your purchase will be re-funded.

After futher investigation, the problem was the same as in this topic.

Namely, after setting both server IP's as shared, instead of dedicated, the transfer went through sucessfully.

Thanks for your pointer!
