How to migrate data from single instance (non-ASM) to RAC 12c (ASM)?

Need to migrate data from a nearly 2 TB database to a new RAC environment. Single instance is on filesystem and ASM is used with RAC. A complication is source single instance has nearly 300 tablespaces and all that data has to be migrated to 12 on destination RAC database. The db names are different too. The new tablespaces have already been created in the RAC database as encrypted tablespaces. What are the options to do this?

One option we are considering is doing an RMAN active duplicate and migrate all tablespaces to the RAC database and then move the objects into the new tablespaces. But that will be very tedious as there are thousands of tables and indexes.

Howdy, Stranger!
