Can we Move my created Document and its dependent reports from one App to Another APP without effecting and raising any Error while this process.
How i can do this task without installing APP on another server.
You need to install same app on another server.
and run command bench update to move changes from development machine to live machine.
Why you want to move documents from on app to another?
You need to do this manually for each document, just open doctype/report created by you and change
Module name to your app.
After changing module name, delete it from your first app.
