It looks like I'm going to have to do a M365 tenant to tenant migration soon (part of company was sold to a new owner). Microsoft's Docs page regarding this basically says it doesn't provide any tools to do it; find a 3rd party tool.
Most of what I've found seems to be only concerned with Exchange. It is looking like I'll have to migrate OneDrive and possibly Azure AD joined laptops as well.
Any and all advise, pointers, and recommendations would be really appreciated.
