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.
