Supported Platforms for Replica Failback

Failback to Original Location

You can fail back to an existing VM in original location from the target host of any version: 2008 R2-2022.

Failback to New Location

If you fail back to an entirely new location or to a new VM in the original location, the version of the target host must be equal to or later than the version of the source host:


Target 2008 R2

Target 2012-2022 (the Target OS version must be higher than Source OS version)

Source 2008 R2

Source 2012-2022



Consider the following exception: you can fail back from the source 2016 host to the target 2012 R2 host only if a VM replica configuration is lower than 8.0.
