How long should I keep older version?

I just upgraded to X2 and was wondering how long I should wait before deleting X1?
Or do I not delete it because I need to keep them both?

Not really a big deal either way...Just looking to free up some space on my HD.

Thanks

BTW the actual program files for Sonar are pretty small and don't take up a lot of space. It's all the extra content that takes up storage but that should go on a separate drive(s) anyway.

You'd lose Guitar Rig as well (edit: You MAY lose it but now I'm remembering that might remain if you installed and registered it correctly). You can do a custom install of X1 to extract any missing plugins without having to install the entire program.

Right on, Mojo. You're gonna love X2 but you might want to keep X1 installed because there is a lot of changes and still a few bugs depending on what type of work you are doing. You may want to make a slow transition as you learn about lanes and the new ways of comping. So a real simple answer to your initial question... I'd say give it a month or so before you uninstall X1. Also remember that if you use any of the new features or gizmos in X2 those elements may not open correctly in X1. If you do not use those features then the project should open fine in X1. Cheers.
