My company provides a suite of software and services that ease the process of data migration. We use a dictionary based approach for describing the meta data and the mappings between the legacy and the new system. The product generates PERL source to actually perform the conversion, so the human/error prone side is eliminated. The tools integrate tightly with ERWIN. If you're trying to support a migration with a large number of tables, or the transformations between the two systems aren't simple, then you'll definately be interested in what we have to offer.
