Migrating from Workgroup to Enterprise

We are planning to move from Workgroup to Enterprise. Is there a migration tool? We don't plan on changing revs and have been on the same rev scheme since implementing workgroup. We also don't use lifecycle management in workgroup so all the files are in the same state.

I have searched the fourm and found reference to a tool but no positive answers.

If there is a tool where can it be found?

Thanks in advance,
