Processor compatibility can support migration between different CPU generations at the cost of hiding newer processor features.
Prerequisites
- Administrative access and an approved change window.
- A verified backup and documented rollback plan.
- A pilot environment or low-risk target for validation.
Step-by-step procedure
- Confirm migration requirements and cluster support.
- Shut down the selected VM.
- Enable migration compatibility for the processor.
- Start and test the workload before migration.
Commands
Stop-VM -Name "APP01"
Set-VMProcessor -VMName "APP01" -CompatibilityForMigrationEnabled $true
Start-VM -Name "APP01"
Get-VMProcessor -VMName "APP01"Verification
The VM starts normally and the compatibility property is enabled before migration testing.
Rollback
Shut down the VM and disable the compatibility property if it is no longer required.
Security notes
- Use least privilege and record the change.
- Review relevant event logs after implementation.
- Test before production rollout.
