I currently have Lightroom 5 and just purchased Lightroom 6. Do I need to do something so that I only have Lightroom 6 on my hard drive? If so, what do I need to do? Do I need to have my hard drive cluttered with both LR 5 and 6 since I just purchased LR 6 ? Please advise how I can address this issue.
You can get rid of LR 5 if you have purchased LR 6
Just to see LR 6 on your computer, remove/uninstall LR 5 from control panel(Windows) finder(Mac)
