Provided your new provider creates a route object that maps to their ASN
beforehand, you need a minimum of 24hrs (and at most 72hrs) for networks
around the world that filter based on RPSL to pick up the changes.

It's not an issue if both route objects exist for the transition. So I'd
take down the old one after you've completed the migration. The main
thing is to ensure the new route object has time to bake in before you
move over.
