We are in the process of updating our imaging system supplier, and we are migrating images for this. Do we need to wait to be on the new imaging system to use NIR?

That would make sense to prioritise the activities in that order, however the planning and alignment conversations, or starting the onboarding process in parallel is recommended to prevent any delays in securing the funding and resources for NIR onboarding. There could be benefit in some cases to connect both, if there are time constraints, or for business continuity.
