If you add a cluster to another backup server and install I/O filter (filter required for CDP) on it, CDP policies on the first backup server will fail. You must configure CDP for one cluster on one backup server only.The target cluster must support hardware versions of VMs on the source cluster (VMs that you plan to protect).

Then, in the Veeam Backup & Replication console, relaunch the CDP policy. In this case, go to the vSphere Client and delete the V eeam CDP Replication vm storage policies as described in VMware Docs. However, if you replicate data within one vCenter Server, and this vCenter Server includes hosts of different versions (6.5 and 6.7), your CDP policy may fail.

You can replicate data between vCenter Servers of different versions.

In turn, all clusters managed by the same vCenter Server must also be of the same major version.

All hosts in a cluster must be of the same major version: 7.x or 6.x (6.5, or 6.7, or a combination of 6.5 and 6.7 is supported).With the previous versions of VMware vSphere, Cisco HyperFlex is not supported. Cisco HyperFlex 4.5 (2a) and later can be used as a source or target only with VMware vSphere 7.0 U2 and later.For supported source and target datastores, see Veeam CDP Source and Target.For supported platforms, see Platform Support.VMware vSphere Essentials Kits editions are not supported. VMware vSphere edition must be VMware vSphere Standard Edition or higher.When using a legacy socket-based license, the Enterprise Plus edition is required. CDP is included in the Veeam Universal License.CDP has a set of requirements and limitations.
