Maybe I should not, but I'm doing it anyway :D 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. With the new functionalities, occasionally a change in the database structure results necessary, and when the change is simple (for example, just adding a new attribute to an entity) altering the data model and the data structures in an old sqlite is far easier and faster than implementing the migration functionality suggested in the documentation. In fact, I think this is faster and easier even when more complex changes are necessary. Anyway... I was wondering if I should take care of the Z_UUID during the perform of this upgrades, or if I can just ignore it. I'm currently ignoring it... can this become a problem in the future?
