there are a variety of "ETL" tools out there that can extract data from 
one database and load it into another.   I was going to suggest 
pgloader, but that doesn't support oracle, only mysql and ms sql server.

a full scale conversion of a complex application suite, however, can be 
a several year project.     Our old Oracle application was very heavy on 
plsql.  We chose to reimplement the vast majority of the business logic 
in appserver modules outside the database and only used plpgsql for 
things where performance mattered significantly.

the more heavily your apps use Oracle specific features, the more work 
the conversion will be.
