Clearpass Backup from a lower version, restore to a higher version

Hi all,

 

Is it possible to restore a backup taken from a Clearpass server, and restore this on a new Clearpass server with a higher version?

If supported, is there a matrix available with the possibilities between the versions?

 

Thanks, best regards,

Martin

Instead, you can join the new node with higher disk space to the existing cluster. This will replicate the configuration and you don't have to manually backup and then restore. 

Then drop the current publisher and promote the newly added node as publisher. You can then upgrade the cluster to 6.9.1.

You certainly cannot restore backup of your CPPM configuration from higher version to lower version. I would expect this to be the same from lower to higher. I've always restored to the same version then upgraded accordingly.

Re: Clearpass Backup from a lower version, restore to a higher version

Typically, we do support restoring a backup onto a higher version. Having said that, we've to consider if there are any internal db schema changes that are backward incompatible. 

What is the backup version and the version you are trying to restore on? I can then confirm if it is supported.

Re: Clearpass Backup from a lower version, restore to a higher version

Hi,

 

Currently the clearpass cluster (3 servers) is running version 6.7.13 within VMWare and we don't want to upgrade because of very low disk space. Instead, we want to deploy a new cluster with version 6.9.1 in parallel. Ideally, the fastest way to do this is backup the publisher and restore this in 6.9.1 and build the deployment again. But as you said, it depends on the internal db schema changes and possible incompatibility.

 

So, is there some kind of compatibility matrix what works between the versions?

 

Otherwise we deploy a new publisher with the same version, restore and upgrade, and then build the cluster again.

 

Thanks and best regards,

Martin

Hi,

Thanks for the information. That is also a very applicable solution.

 

So I take it there is no compatibility matrix, or it is not possible, for restoring a backup from a lower to a higher version? That was my original question. If not, the alternatives will be applied.

 

Thanks and best regards,

Martin

Spoiler
 

I have tried to back up like this, it is not possible, only the same version.
