How to update the version of the application in the AppStore without errors?

Question

Objective-C

Tell me, how is the process of updating the version of the application in the AppStore?

For example, I downloaded the first version of the application, and then made some global changes, which in the simulator, when the application is launched with old data, it throws an error, but by deleting the application completely and rolling the new version from scratch, everything is ok. What will happen to such an update when I upload it with the next version in the AppStore for those who already have the previous one installed?

There will be a flight. You need to implement the migration.
