Which requirements are temporary in nature?

Transition requirements are the only category of requirements that are temporary in nature. They define the capabilities that a solution must have to facilitate the transition from the current state to the future state, but they are not needed once the transition is complete. These include data conversion, training, and deployment needs.

They support the implementation but are not part of the long-term functioning solution. This distinguishes them from business, stakeholder, and solution requirements, which are ongoing or permanent once implemented.

BABOK® Guide v3 – Section 2.3.4: Transition Requirements:

“Transition requirements describe the capabilities that the solution must have to facilitate transition from the current state to the future state, but that will not be needed once that transition is complete.”
