How to uninstall OmniFocus 1 and 2-beta?

Now that I’ve installed the paid upgrade to OmniFocus 2 Pro, I still have OmniFocus 1 and the OmniFocus 2 beta running. How do I uninstall OmniFocus 1 and 2-beta without deleting anything essential to OmniFocus 2? Can I delete the OmniFocus 1 and 2-beta app icons and then run CleanMyMac (an uninstaller utility) to delete all files associated with OmniFocus 1 and 2-beta? Or are there specific OmniFocus 1 and 2-beta uninstallers?

To uninstall an old OmniFocus app, yes, you can just delete the old .app bundles. In the past, though, we’ve encountered some problems with apps like CleanMyMac erasing caches important to running copies of OmniFocus. You can consider OF1 and OF2 betas uninstalled after simply deleting the apps.
