Hyper-V 2016 and 2019 Failover and Failback

Post by Manuel Monteiro »

Production environment:
Two WS 2016 Hyper-V hosts connected via iSCSI to a storage

Potencial DR environment:
One server with WS 2019 Hyper-V with local disks.

Production environment will use Veeam replica for VM replications to the new 2019 Hyper-V host.
Question: Will I find any trouble in failover to a new Windows Server with Hyper-V role and then failback to an older version (2016)?

Yes, you will with Failback. The target version will be lower than 2019 so it will not work. See this for info - https://helpcenter.veeam.com/docs/backu ... ml?ver=110

Note that the Target has to be of the same version or higher.

Note that the failback will work. You can failback to the original vm without any issues after sorting out any issues you have with the production environment.

Failback to a new location is not possible for 2019 to 2016. That would mean to build a new replica relation ship, which needs the same or a higher hyperv version as the source host. That would be the case, if you have vms on your 2019er servers which needs to be replcated with a new job to the old 2016.

Chris posted a link with the correct answer:
You can fail back to an existing VM in original location from the target host of any version: 2008 R2-2019.
