It is possible to provide new updates for the existing users while not having any more new users download our app by removing the app from sale ?

Hi, after 2 years of not updating my app on appstore i wanted to submit an update for my iOS app which also containts a watch app target. When i try to submit it to upload it i get the following errors: Failed registering bundle identifier The app identifier "(myappBundleID).watchkitapp" cannot be registered to your development team because it is nit available. Change your bundle identifier to a unique string to try again. No Profiles for "(myappBundleID).watchkitapp" were found. Xcode culdn't find any iOS App Store provisining profiles matching "(myappBundleID).watchkitapp" Since i have my app already in store with that bundle identifier i don't know why it can not be registered to my team. Also i don't want to change the bundle identifier because then i can not publish it as update to store.
