Do we have an exact timestamp in UTC when the Rental to PPU migration will happen? Or the time window when it will happen?

Actors will be migrated in random batches, so we can't give an exact timestamp for any one specific Actor. Assume that migration will kick off at midnight, even if any of your Actors don't migrate until later in the day. From what I can see, you don't even have any Actors left to worry about...

Haha that's true! Thanks for your answer anyway!
