A general system error occurred: Warning: This virtual machine is protected by VMware Site Recovery Manager. Migrating the VM from a replicated and protected datastore 'Health-xxx-xxx' to a non-replicated datastore will cause the VM to become non-replicated and you will not be able to recover the VM using Site Recovery Manager in case of a disaster. Do not proceed unless you understand the potential data loss involved. Note: You can migrate the VM to a datastore that resides in the same consistency group as 'xxx-xxx' without any issue.
