Restore configuration on CUCM from BACKUP

[li007il89]

Hello,

Could you please help me with a such question.

I've installed a new CUCM server ver. 12 and want to upload backup from my old server ver. 10.5.

Is it possible or I need to upgrade my old server from 10.5 to 12 and then make backup and upload it on a new server?

Does my backup file contain such information as ip address, hostname, certificates, administration users, security password? Could it change this parameters on my new server after backup upload?

Best regards,

Uladzimir Hryharovich

A restore will only work on the exact same version from which it was taken.

The DRS guide explains the procedure, and what information needs to match for a backup to be restored, review the online documentation.

Yes, you can change whatever you want after you restore.

Thanks Jaime for your quick answer

Do I need to have the same aplication user/password, OS admin user/password, security password on my new CUCM server as on my old one if I want to upload backup on it.

What could happen if I will have another OS admin username/ password on my new server.

Best regards,

As I previously mentioned, the DRS guide lists ALL the requirements that need to be EXACTLY the same as they were in the server from which the backup was taken in order for the restore to be successful, have you reviewed the documentation??

Not sure if you asked if the backup will overwrite the data, if so please note the below points as well, The hostname, IP address, DNS etc has to be the same on the 12.X cluster as the 10.5 one.

Be aware that DRS encryption depends on the cluster security password. If you have changed the security password between the backup and this restore, DRS will ask for the old security password. Therefore, to use such old backups, you must remember the old security password or take a backup immediately after the security password change/reset.

If you are restoring Cisco Unified Communications Manager, ensure that the Cisco Unified Communications Manager version that is installed on the server matches the version of the backup file that you want to restore

When you perform a DRS restore to migrate data to a new server, you must assign the new server the identical IP address and hostname that the old server used. Additionally, if DNS was configured when the backup was taken, then the same DNS configuration must be present prior to performing a restore.

Thanks Aeby for your explanation

Instead of doing Fresh install consider doing PCD Migration which will allow you to migrate existing date onto new 12.0 system in single job.  With PCD you also have a choice of retaining existing IP/Hostnames or changing them.

Thank you Chris for your answer.

If I will use PCD for migration do I need to install a new cucm 12 server before migration or PCD do it by itself?

Best regards,

You only deploy the blank OVA that you need, PCD will use bootable media to perform the install and migrate the data.
