Hi @lancecontreras

Typically the flow is: attempt to open the database, if it fails, attempt to migrate, if that fails then the key material is incorrect.

My colleague @sjlombardo gave further details in his response here: [Upgrading to SQLCipher 4](https://discuss.zetetic.net/t/upgrading-to-sqlcipher-4/3283/17)
