The roles have been activated.
You can now proceed with the migration whenever you want from the Roles tab of the project settings.
The process is fully transparent for the users and no interruptions will be caused even if you perform the actions during work day.
The process will only take a few minutes.
(Corrected: Please forget the first message about the pending invitation, it is irrelevant)
Have a good day @Maximiliano_Carrizo
Best regards,
Shohan
