What is the method for publishing content without erasing user data?

edit

One method for publishing content without erasing user data is to use a staging environment. In this method, the website or application is replicated on a separate server environment where the changes can be made and tested. Once the changes are finalized and tested, they can be pushed to the live server without affecting the user data. It is important to ensure that any new code or files are compatible with the existing user data and that all necessary backups are in place before making any changes to the live server. Additionally, any user data that needs to be migrated or updated should be handled carefully to avoid any loss or corruption of data.
