title: Migrate normal sqlite3 database to core data?
body: <p>I have a normal pre-populated database. I want to migrate it to core data for my app. What is the best way to achieve this. By the way I have done these things, copied the recipes.sqlite database from apple's sample.exported a table sql. Rename the column names according to the core data table columns(something like this - id "primary key" with Z_PK). filled that table with my values. But i am unable to understand the columns names Z_ENT and Z_OPT. Does some one knows how do i migrate my prepopulated sqlite3 database to core data easily. </p>
  
  <p>Thanks</p>
