Hi @Chae
According to our official documentation, legacy licenses won't automatically transition to the new licenses. Upon expiration of a legacy license, you'll need to purchase a new Teams Rooms Pro or Teams Rooms Basic license.
If you have existing Teams Rooms Standard or Teams Rooms Premium legacy licenses, you'll need to switch to Teams Rooms Pro when your legacy licenses expire. If you have an Enterprise Agreement, you'll need to switch to Teams Rooms Pro licenses at your next renewal period. For more information, see Switching from Teams Rooms Standard and Teams Rooms Premium.
