When recovering a protected Hyper-V environment after a disaster or when migrating VMs to a new environment, you can move to a new Agent version and recover Agent jobs and settings from the previous Agent version. For example, you can move from Hyper-V Agent 7.30 in a Windows Server 2012 environment to Hyper-V Agent 7.40 in a Windows Server 2012 R2 environment, recover backup jobs, and back up VMs in the new environment using the recovered jobs.
To upgrade the Hyper-V Agent when migrating to a new environment:
1. Create a new Hyper-V environment.
2. If possible, migrate VMs from the original environment to the new Hyper-V environment.
3. Install the new Hyper-V Agent version in the new Hyper-V environment. See Install the Hyper-V Agent Management service and Install the Hyper-V Agent Host service.
4. Recover jobs and settings from the earlier Hyper-V Agent version. See Recover jobs and settings from an offline Hyper-V Agent.
5. If the original protected Hyper-V environment is lost or unavailable, or VMs cannot be migrated to the new environment, restore protected VMs to the new Hyper-V environment. See Restore Hyper-V VMs.
6. Enable all scheduled jobs for the new Hyper-V Agent. See Disable or enable all scheduled backup jobs.
