V8 & V9 compatibility Veeam

[adrianIDC]

I have in my lab to test veeam v9 .

At the same time I have to veeam production v8 for backup job .

I 've watched that copies are not made a host hyper - v

Indicating the reason is that the version of the console is not compatible with veeam v8 .

This hyper-v host is added to veeam v9 for backup test.






As I can solve this error ?

I remove the hyper - v host from the console v9 ..... and again I add it in v8 ?

Hello adrianIDC,

I remove the hyper - v host from the console v9 ..... and again I add it in v8 ?

Makes sense - remove host from v9 console and then it should be possible to add it back to v8.

[adrianIDC]

Yes, it's what I had to do.

Thanks

The behavior is expected. Once you've added the host in v9 console, the Veeam B&R components installed on it were upgraded to the new version, which v8 console cannot communicate with. Adding the same servers into two Veeam B&R consoles of different versions is not supported.

Happened to me today, I manually uninstalled the Veeam modules on the host and imported the host again in V8.

It would be nice if this was possible for a large environment to transition from v8 to v9 on multiple servers instead of having to upgrade everything at once.

You can install separate VB&R v9 server and start to add hosts to it one by one, waiting some time before adding a new one, to make transition from v8 to v9 more smooth. Thanks.

You would also need separate backup repository and off-host proxy servers to do that, no?

[veremin]

You're right, indeed, repository and offhost proxy components must have slipped from my mind. So, your feedback has been heard; appreciated. Thanks.

Hi,
Proxy and backup server only communicate if they run same version (we cannot mix versions), but can a CIFS repository be shared between a v8 and a v9 veeam infrastructure ?
What about a Windows repository ?

[alanbolte]

CIFS repositories can be shared between different versions of the software so long as they use different gateway servers. Communication between a gateway and a NAS is just SMB protocol, it inherently has nothing to do with your version of Veeam.

Windows repositories cannot be shared between versions.

I've seen Linux repositories shared between versions in the past, but I haven't verified that recently.

The CIFS repository can be set both v8 and v9. The only thing that can not be is the server itself hyperv
