Upgrading SilverStripe Elemental from version 3 to version 4

Silverstripe Version: 4

Question:

Any suggestions for upgrading DB content for SilverStripe Elemental when upgrading from version 3 to version 4?

We are working on a upgrade at the moment and looking for some tips for upgrade the DB. For example:

Entries in the WidgetArea table with ClassName Element need to be moved to the ElementalArea (and ElementalArea_Live as well?) with ClassName changed to DNADesign\Elemental\Models\ElementalArea. OwnerClassName also needs to be added for each record.

If anyone has any tips or code that could help us speed up this process it would be much appreciated.
