Veeam Backup for Microsoft 365 in-place OS upgrade

[lucaliga]

Hi,

there are many topic about Windows server in-place OS upgrade when Veeam B&R is installed. I can't find here topic on in-place OS upgrade when Veeam Backup for Microsoft 365 is installed. We would like to perform in-place upgrade Windows Server 2012 R2 to Windows Server 2019.
Veeam suggestion ? There are users's feedback about it ?

Thanks
Regards

Hi,

We are actually testing such scenario's for our upcoming release, as we will need to drop support for 2012 and 2012 R2. I have not yet received the final test results from QA, but from our own testing, it worked perfectly.

(By the way, even in our own testing, we always took a backup from the entire server upfront (which you can do with VBR if it is virtual or the agent if it is physical). Just as a precaution...

Did we ever get official guidance on an in place OS upgrade especially if this was being tested internally. I cannot see anything still in the documentation etc.

Hi,

We just upgraded our VBO 8.1 Win Server 2019 to Win Server 2022 in place upgrade.

No issues, just 1hour/30 min downtime.

Works as expected. Remember to OS updates after OS upgrade.
