We're already working on a project but realized that we can't make changes to the existing structure of database, which we have accidentally done already. So in order to upgrade, we are setting up a new server and want to migrate all APIs from current server to new server.
While doing this, we need to take special care that we don't copy over the mistakes that we have done previously. One of the mistakes is adding new columns to existing table structures. So, in case we need any such thing, we need to create a new relational database table and will make the new columns in our tables to adjust it.
