I was told by MV Support, without really any explanation as to how, that it was possible to import projects from an old deauthorized version of MV to a newer version. I had 2019 and moved to 2023. My question is, if I need to export a project but don't have access to the old MV to export and create the .sdf file, then how can I successfully import the project to the new version without first exporting and creating that file? I have looked through the community and knowledge base and couldn't find the answer. Any help would be appreciated. My only though at this point, is to spend a huge amount of time exporting my entire projects library from the old version before deauthorization takes place. 

I can't afford to screw this up and I don't have enough knowledge or confidence to do this without better instruction.
