Replication error 11.3

Hi All,

I have 2 systems on 11.3 and I'm trying to replicate a ZVOL from one system to the other. I keep getting the following error.

Source 'ISCSI_Storage/Backup Storage' is a volume, but target 'Replication_Pool/VeeamBackupRep' already exists and is a filesystem.

Not sure what i'm doing wrong.

Thanks
