When attempting to reconfigure a protected virtual machine to change its target datastore in vSphere Replication (8.x or 9.x), the reconfiguration wizard displays the following warning:
"Existing replica disk might not be compliant with the new storage policy. Virtual machine may recover with warnings."
The user may be unable to proceed without acknowledging this prompt, or may fear the replication will become unhealthy.
This is a proactive, non-blocking administrative notification. It occurs because vSphere Replication detects a discrepancy between the capabilities of the selected target datastore (or the existing seed disks) and the rules defined in the VM's assigned Storage Policy.
Because the replica disk is not yet "active," it cannot always be automatically remediated to match the policy rules until a recovery operation (Test or Disaster Recovery) is performed.
The warning is safe to acknowledge and does not impact replication health.
