Okay, well, I was able to follow this link and literally copy the repository files to the windows server to preserve the old repositories. The only thing that didn't copy over properly was the user.conf. for some reason it would not recognize the users when I tried to connect from my dev machine. So I recreated the users using umtoolgui.exe. This makes me wonder if I put the old user.conf in the wrong folder with the repos because I just noticed a new one in the install folder - same folder as umtoolgui.exe.
Anyway, my old repos are successfully transferred from the old Linux box to the new Windows 10 box and I can see them on my dev box. But I was reading how great the Jet db is and was wondering if I can use the "Migrate database backend" in the Plastic SCM Server administration tool to convert the sql lite repos to Jet? If so are there any blogs or links someone could share how to properly do it? It seem straight forward but I don't want to assume. What's throwing me off is the request for prefix and suffix.
