Cisco Cisco Expressway Release Notes
Limited testing has shown that this feature works via MRA. Hence this feature is in preview with Expressway X8.5.1
and later, pending further testing and full support in a future version of Expressway.

Note:
This feature is distinct from the multiple deployments feature released in X8.5. That feature is limited to one
domain per deployment, where all IM and Presence Service clusters within a deployment serve a single domain. This
feature is different because it concerns MRA support for all IM and Presence Service clusters within a deployment
serving a common set of one or more Presence domains.

Each new domain impacts the Expressway’s performance. We currently recommend that you do not exceed 50
domains.
