Do I 'need' cloud commander for purely a mailbox migration

HI all,

We have a divestment from an on-premise estate to a new tenant; new as in, different from the 'parent'

EG:
company.com is divesting from Parent.net, moving into Azure in its own tenant. Timescales prevent a tenant to tenant migration as parent.net aren't looking to go into the cloud for 6months

We are looking just to use migration manager-we know the potential of the whole suite of tools but just looking to get email over the fence.

This tool, retaining the permissions & delegate permissions is going to be sooooo handy! but does it need cloud commander ?

many thanks in advance
