CMMVC1056E The command failed because Global Mirror is either not supported on this system or not supported on the remote system.

Explanation
Global Mirror is not available in the code version on either this system or the partnered system
as it is replaced by asynchronous policy-based replication.

User response
If you need to continue the use of Remote Copy, then convert the relationship or consistency
group to Metro Mirror to provide synchronous replication. If you need asynchronous replication, then
configure the asynchronous policy-based replication instead.
