What happens on migration - what happens automatically and what happens at our discretion? - do we get a warning? - do we need to opt for migration? - does everything get migrated in one block migration? - does everything that was in Video the next day appear in Stream? - do we then close down Video?
Once initiated the transtion will take a bit of time and we'll do it as a live sync as changes to O365 Video happen we'll sync it to Stream. Once we catch up with the bulk of migration you can preview it in Stream. Then you'll have to finalize the transition which will make all the redirection logic kick in for all users so links and embeds from O365 Video go over to Stream.
We'll move over channels, videos, permissions etc.
