Just a quick warning:-
You do not get to find this out or be told until AFTER the migration!
If you use the type "yes/no in your document custom properties this will not translate to "yes" or "no" in Solidworks PDM,
This will translate to "0" or "-1"
If you require to have"yes" or "no", you know the way it was, you will have to update each and EVERY document that contains this type MANUALLY.
Months ahead now of fixing something that wasn't broken.
