I installed LR 5. Is it safe to uninstall LR 4, or will it mess up my catalogs?
When you installed LR5 it created new LR5 catalogs. Your LR4 catalogs are still there but will not be used by LR5.
You can uninstall LR4 if you want and the new LR5 catalogs will be unaffected.
There is no rush to do this so make sure LR5 is working to your satisfaction first.
