Mentor Integra to Altium

[emballage]

Hi there,

I have a annoying issue and need your help. Because of reasons I need to work with projects created by a software called "Integra", which was a product of mentor graphics (In the 90s?). Using this very old software in a VM is pain. Did anyone figure out a way to convert those old projects to Altium? Or maybe to some version of Mentor and then to Altium? That would be awesome.

Thanks in advance!

Best regards
