Recently I stumbled in a new challenge I haven’t had for a long time. One of my customers wants to migrate users from Active Directory Domain A to Active Directory Domain B. The problem was that all the previously edited documents should get mapped to the new users.
When you migrate SharePoint 2010 to SharePoint 2013 or to Office 365 some of the views that was created in the previous version might look the same.
The user will get a mixed user experience because document libraries, switch between the old view styles to views that are configured for client side rendering. Via scripts those views can be recreate, but they also can be upgraded in-place.
