Expdp/impdp is better if you are on a suitable platform (10g onwards IIRC). In that case do not drop the user cascade but drop objects belonging to the user (I generally find this to be quicker and we have a procedure to do it)
Ensure all tablespaces exist on target that are used by that schema on source (and you have quotas).
Gather_schema_stats afterwards on the target schema execute dbms_stats.gather_schema_stats('DEV',10,FALSE,' ',2);

Subject: Method for migrating schema from PROD to DEV
Does anyone have a proven method for migrating a schema from PROD to DEV? I plan on using export/import, but I've got a few reservations about the migration steps.
I think the best method would be to do the following
- Export Schema in PROD
- Export Schema in DEV (for backup)
- Drop user in DEV
- Create basic user in DEV
- Import user in DEV
- Verify object count - PROD vs DEV
- Compile schema
Does this sound right?
