the python log shows the code failed at db.create, didn't see how it's related to the database file-copy in the code? Have you tried to run the steps manually? Because I used the ToDo app tested 1.4 -> 2.5 unencrypted db upgrade manually, it didn't have an issue to load old version of db.

Yes, I've checked. Create method works like this - if a db with that name doesn't exist than it creates a db with that name and returns db object. If db with the given name exist, it just open up (in case db is of lower cal version, it tries to migrate it) and returns db object. If you check the logs, it was migrating cbl-1.4 db to 2.5, when it crashed. For much more clarity I've added add log.

It seems there is a flaw in cbl logger. It is not able to dump data fast enough to catch app crash.

Let me know if you have any other doubt

We'll need the logcat to get anywhere with this. Please attach it.
