In a migration, the new version is installed side-by-side with an existing version of QPR ProcessGuide Xpress and you can proceed with the new version's installation similarly as if it were a first-time installation of QPR ProcessXpress. The default installation folders are designed not to overlap, but if you have used a custom installation folder, make sure you're not installing the new version into the same folder with the old one. Note that once you save your models with the new version, you cannot open them in the old version anymore. When you have taken the new version into use and are satisfied with it, you can remove the old version using the Windows Control Panel.

Note: Make sure you have full backups of your models before proceeding with the migration!
