Hello All,
I need to migrate vm linux server from OVM to KVM. For migration I use ReaR toll. After migration there are same: os version, ip-address hostname, users, all(it is clone of old server) on new server. Problem is, that on server there is installed Weblogic, which does not start after migration .
OS part of migration works fine, but application part doesn't. Ror migration of application, I tried to use backuppc,networker and Rear. No matter what I try , the result is same. Weblogic does not start.
Can you please advise me some "how to" on how I can copy/migrate weblogic from old server to new? I don't known this application, but i need to migrate these servers.

How can I backup Weblogic? Because via tools BackupPC or Networker, the data from backup are not usable.
I tried to clone one VM on OVM, and I deleted the volume where WebLogic was installed , and then I restored it back via both mentioned tools. In both cases it wasn't possible to start application weblogic after FS restore. What is so special in this application, that it isn't possible to backup/restore it or copy it to other VM?
We migrated a lot of servers via ReaR toll with lot different application as MySQL, Docker, Apache, Jenkins, Jboss, OracleDB and many others and there weren't any migration issues. problem is only with Weblogic.

Generally speaking, you can't just copy the Middleware Home and expect it to work. You are meant to use the supported tool, the cloningclient.jar utility that you will find in $MW_HOME/oracle_common/jlib
Trying to do it manually will be a nightmare task. For example, do you know how to reconfigure the wallets? Or the repository database schemas?

I have pointed you to two solutions already: the supported techniques for moving a machine from OVM to KVM, and for cloning a Middleware installation. If you don't want to try them, I don't think I can do any more. Perhaps someone else can assist.
