Migration on 40 schemas with a total size of 300GB

Hi,
I'm involved in a migration project with Golden Gate 11.1 from a source 9i single instance EE database to a 11.2 two-node RAC SE database.

Because it is a EE to SE migration I'm forced to use an export/import-like load method to do the initial data load (besides that the client wants to compact tablespace space).

This 9i database has been in service many years and their schemas have a lot of object dependencies with other schemas. I've identified a self-cointained group (in terms of object dependencies) of about 40 schemas with a total size of 300GB.

Based on you experience, what is the best approach to do the migration using Golden Gate? I mean, best data-load method?, convenient/necessary to have a single extract/replicat group pair for all the schemas? a "magic" solution to do the migration in smaller "chunks" to avoid the full 300GB data load?

Howdy, Stranger!
