At this point it's maybe not worth the effort to find out. A related problem is that the IDE and most VB6 controls and apps are awful about littering all of their settings in the Registry (where it doesn't belong) or equally hard to find spots. Most of the VMs I've seen you can't even rebuild at this point: they were lifted and shifted from some distant past developer's machine and nobody anymore has the raw license codes or files to unlock the various third party components (and some of those component companies no longer exist, so good luck). I imagine that's a problem many projects would face trying to use the RAD Basic IDE, too and I don't think it's possible for it to be "no migration", because there will be components that won't work, won't relicense, etc.
