Migration to a new group

[Christophe Humbert]

I need to migrate an Office 365 group from ProjectName@mytenant.com to NewProjectName@mytenant.com. The group mainly hosts e-mails and calendar events, also some SharePoint documents.

How could I accomplish this? I didn't find any guidance in the Microsoft documentation.

Renaming is not an option, I need to free up ProjectName@mytenant.com as it is going to be re-purposed.

There is not a buitin process to do such migration Today in Office 365...what you have are PS Groups cmdlets and Graph API to help here
