The retirement plan

What is being switched off, when, and what has to move before it can be — because adopting without retiring is how tool sprawl happens.

The deliverable

What it is

Adoption without retirement leaves two systems and one fewer source of truth. It is the normal outcome, because retiring is work with no visible benefit.

The retirement plan should be written at the same time as the adoption decision, since afterwards there is never a reason to start it.
