Which licence do I need if I want to migrate a user with multiple teams in teams


My colleague want to migrate a lot of users with a lot of teams in teams.

They are like 60 users and all of them have (or they are part of) multiple teams.

He bought the collaboration licence but he was only able to migrate one user and one team.

Which licence do we have to take to be able to migrate a user with all the teams he has or he is part of ?

Thank you for your help

Hello does anyone have an answer please ?
