Copy and update master pages and page layout
Have the ability to migrate and update automatically master pages and page layout when migrating a site.
I would highly recommend, since SP2007 is still in play and it causes issues with Masterpages that don't work, that you de-select the masterpages folder by default and allow the user to determine if they want to include that folder or not.
We would like to be able to apply a new masterpage to an entire tenant by coyping the masterpage to the root site collection of the tenant and using Sharegate to apply that masterpage to all site collections in the tenant. We have found that if there are hundreds of site collections, this process can be very time consuming.

Since the destination is always the same version of SharPoint, I'd like to be able to duplicate the Master Page Gallery content as well as the look and feel. Currently, there is a lot of manual work involved after a duplication.
