Migration My Meetings

[Chiho]

We have two contracts of Zoom. One has one account (named "A") and the other has five account (named "B"). We are going to cancell the A because 6 accounds would not be needed (5 is enough). However, with in the A, there are a lot  of my future meetings alrealy set and I would like to migrate the meetings into the B. Are there any good ideas that we don't have to recreate the meetings?
