Re: adding new columns to table
Using Flyway (or Liquibase), you'll have to extract the JDBC connection from Cayenne to pass to Flyway to perform the migration when the application initializes. See the bottom of: http://flywaydb.org/documentation/api.html Also, Flyway doesn't know about Cayenne, so you'd have to update your Cayenne model to have your new column(s) then add an SQL script (or Java migration) for Flyway to use to upgrade the schema separately. Not too difficult, just something to keep in mind to be part of your process. mrg On Sun, Nov 25, 2012 at 10:45 AM, emeka okafor emeka_1...@yahoo.com wrote: Thank you for your suggestions; I am going to try both and see which one is easier.

Re: adding new columns to table
I've been using cayenne+flyway in a maven3 project... its a pleasure ;) its true that they don't integrate but, till now it does not been a problem for me :) 2012/11/26 Michael Gentry mgen...@masslight.net Using Flyway (or Liquibase), you'll have to extract the JDBC connection from Cayenne to pass to Flyway to perform the migration when the application initializes.

Re: adding new columns to table
Also liquibase is really good, especially if you support multiple database types.
