When changing an app code, make sure to keep in mind the following.

• Changing an app code will remove any links that were automatically created using "Record number" field values that contain the previous app code.
  
  
• If you set an app code that was used with a different app in the past, any automatically created "Record number" links that include it will be replaced.
  This means that any such links that were automatically created in apps or spaces will start linking to the app to which the app code is currently set.
  
  
• Changing an app code will change the "Record number" field values of the records for the app. Be sure to keep this in mind when exporting record data to CSV files or using APIs.
