Changing data source without resetting all column schema

Hi. I have an app that was working perfectly on AppSheet till now. But I have a problem with the current data source(Microsoft 365) and I want to shift the back-end sheet to another Microsoft account. Is it possible to change the data source from my old email to my new email if all the data is replicated in the new email? If so, how can I do this so that I don’t need to work on the column schema(which would take a lot of work and would be like creating a new app)? I need all other settings to be the same just the data source to be from a different email ID. Any help would be appreciated.
