Challenge
A replication job fails with the "The operation is not allowed in the current state" error message.
Cause
When a replication job runs for the first time, Veeam Backup & Replication creates a VM replica on the target host. This VM replica has the same configuration as the original VM. If the version of the original VM hardware is higher than the versions supported on the target host, the VM replica cannot be created.
You can check the hardware version of the original VM in vCenter. For this, select the VM and open the Summary tab. In the VM Hardware section, you can see the following information:
The full list of ESXi/ESX hosts and compatible VM hardware versions is available in this VMware KB article.
Solution
You can resolve the issue in the following ways:
- Downgrade the version of the original VM hardware. For details, see this VMware KB article;
- Upgrade the target host.
