Upgrading from an older RAS version

If you have an existing Farm running RAS v16.x and would like to join it as a Tenant to Tenant Broker, follow these steps:

1. Upgrade the Farm to RAS 17.1 (or newer).

2. To join your Farm as a Tenant to Tenant Broker, follow the instructions in the Deploying Tenant Broker and Tenants section.

3. Once the Farm is joined, you can remove local RAS Secure Gateways if you are not planning on using them for local connections. See Implementation overview for additional info.
