It's a nice tool but I'm wondering what it's telling me. Assumedly because they weren't imported to the dev environment in the same order, some custom entities have different ObjectTypeCodes. The utility reports difference like this:
<returnedtypecode formattedvalue="10,017">10017</returnedtypecode>
vs
<returnedtypecode formattedvalue="10,006">10006</returnedtypecode>
Does CRM care? Will it resolve on entity name or is this a cause for colision?
