Hi All,

I need to implement data migration in my app. I have an sqlitedb which is 
synchronized to cloud. my problem is to find best way to handle data 
migration on app update.

my questions are below.

- does my existing data and database get deleted on app upgrade ?
- is it possible to invoke a method on successful installation / upgrade ?
- is it possible to bundle an empty db with app in playstore ?
- is it possible to change the database schema of existing db or i need to 
create new db with new schema and migrate and delete old db ?
- what is the best and google recommended way to handle this ?

regards
j
