DMO: Identity column trashed by bulk copy

I'm using the SQL-DMO BulkCopy object in VB 5 to transfer data between servers. It is important to maintain the existing identity values since they are referenced by other tables, so I set the BulkCopy.IncludeIdentityValues property to "true" on both the export and import sides, but the identity values are regenerated by SQL Server nonetheless when the import is done.  I also tried running the "set tablename identity_insert on" query before doing the import, which normally would allow explicit insertion of identity values, but it made no difference.  Any ideas?

OK, I tried all 4 permutations of BulkCopy.IncludeIdentityValues = true/false and Database.Execute("set identity_insert tablename on/off").

The resulting exported data file doesn't have any identity values in it, regardless of what I do with these flags.

Try running

set tablename identity_insert on

on your source table before the export AND on your destination table before the import.

Use the option
-E with bcp (explicit identity)
when loading data, this will allow you to keep the identity column as it comes with the file.
