It depends somewhat upon the size and complexity of your current
implementation, but tools such as Apache's DDLUtils can be of help.

http://db.apache.org/ddlutils/

There's also a long catalog of tools which work with Derby available
on the Derby wiki at http://wiki.apache.org/db-derby/UsesOfDerby perhaps
there is some other tool there which meets your need.

In general, you'll face issues such as:
- converting the database schema, which is often a place where databases differ
- migrating your data, by unloading it from your existing database and loading
it into Derby. Derby provides facilities for loading data in a variety of formats.
- converting your SQL in your application, if you used any non-standard SQL
extensions
- dealing with things such as triggers or database procedures, which generally
are non-standard and will need to be re-written.
- learning the mechanics of Derby, such as how to start/stop/operate/administer it,
and how to build and run your Derby applications.

The mailing list is a great resource; there are many experienced Derby users
who would be glad to answer more specific questions as you encounter them.

Welcome to Derby!

thanks,

bryan
