There are several considerations when you create a replication link.
- You cannot create a replication link between a release 9.x HCP system and a system earlier than release 8.0.
- You can create a replication link only after you have installed the required SSL certificates.
- You can create multiple replication links between the same two systems. However, the links cannot include the same HCP tenants and default-namespace directories. Also, only one of the links can be used in an erasure coding topology.
- If you do not want HCP tenant-level users to see replication details, you should clear the option that allows this behavior before you create the replication link.
