1. Retrieve the identity value with which you want to continue.
2. Create the new table WITHOUT the identity property.
3. LOAD the data
4. ALTER TABLE ALTER COLUMN to make the column an identity column again.

Alternatively you can use the IDENTITY OVERRIDE (sp?) option of LOAD and
alter the table to RESTART with the new value.
I have posted a stored procedure that "synchs up" identity columns after
load repeatedly in this forum.
