There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
What is the exact build number you're using for Xeams?
Could you send a copy of your Xeams.log to our support department right after running the migration tool. Send it to support@synametrics.com
