Question

A team wants to upgrade their documentation agent (v1) to a newer version (v2) that uses a different output format. Five other agents currently depend on the documentation agent's output. A direct cutover to v2 would break all five downstream agents simultaneously. What approach BEST minimizes risk during this lifecycle transition?

Accepted Answer

Deploy documentation agent v2 alongside v1 using versioned routing, migrate dependent agents to v2 one at a time while v1 remains in service, then decommission v1 after all dependents have migrated. — You don't pull a ship's engine while it's sailing — you swap it engine by engine at port. Run the new documentation agent alongside the old one, route dependents one at a time, and keep the old version live until every consumer is validated. That gives you rollback at each step and avoids breaking all five dependents at once.

Answer

Stop all six agents at once, update the documentation agent to v2 and all five dependent agents to the new output format in the same maintenance window, then restart every agent simultaneously once the updates land

Answer

Update the documentation agent to v2 immediately and let the dependent agents fail; they will adapt when their next run encounters the new format.

Answer

Ask the documentation agent v2 to produce both old and new format outputs indefinitely so no migration is needed.
