Unfortunately, CONSISTENT=Y has no bearing on sequences. Sequences are
exported prior to the tables. If you are exporting even a mildly busy
database, your sequences will be out of whack. This is true with exp and
expdp (at least through 10gR2).
If your database is coded to 'auto-increment' sequences based on a table
trigger, I have a fairly non-trivial PL/SQL package I could share that goes
through all the tables in the schema to find the max PK and recreates the
sequences if they need to be recreated.
