I'm looking inside and also I'm manipulating the structure and data of the
sqlite file since about 200 revisions in my project. I'm doing this to
provide newer versions of the app that has the possibility of performing
database migrations / upgrades from older versions of the app if available.

My recommendation is that if you cannot use the Leopard Core Data migrator, that you migrate your data using the Core Data API and not work with sqlite directly. It is possible (but tedious) and will insulate you from implementation details in the sqlite stores. It also will have the advantage that your code should work as-is (or with minimal modifications) with other store types.
