For faster import process you may try:
- Script all indexes, PKs and other constraints in your target database.
- Drop all indexes, PKs and other constraints -keep only flat empty tables in your target database.
- Import with indexes=N constraints=N ignore=Y options
- Check import log, when flawless go ahead
- Build/create indexes, Pks and other constraints using script from step #1
- Gather fresh stats
Hope this helps.
