2.1 Rolling Upgrade Restrictions

Take note of the following restrictions if upgrading an RTR environment from

RTR V3.2 to V4.0.

The RTR recovery protocol consists of messages sent from one backend, via

a router, to the target backend. If either of the RTR backends is upgraded

to RTR V4.0, then the router that will be used for recovery must also be

running RTR V4.0. This generally means that any RTR router nodes should be

upgraded to RTR V4.0 before any RTR backend nodes. There is no restriction

in the order that RTR backends should be upgraded to V4.0.

The order in which RTR nodes should be upgraded for a rolling upgrade from

V3.2 to V4.0 is as follows:

1. Frontend-only nodes can be upgraded at any time

2. Router-only and mixed frontend/router nodes

3. Mixed router/backend nodes

4. Router-only nodes

5. Backend-only nodes
