I have created a suiteApp in a demo account and create bundle of it and install that bundle as a suiteApp in a client's account. Now I want to copy that bundle to another account and delete the bundle from demo account without effecting the work done in client's account. Is there any way to do that?? Or link copied bundle to suiteApp Installed in client's account??

you can deprecate the old bundle by the new bundle and customer should not be impacted.

okaayyy..thanks
