How to move 200 materialized views without having to re-create in the new home
If you are moving the database (backup on old server and restore on new server) the MVs will come along.

Are you creating an empty database on the new server? If so you could use Data Pump to export the MVs from the old and import them into the new.

I would opt for using a full RMAN (or filesystem) backup and restore over Data Pump.
