Fast copy of data from one table to another

I have to copy the contents of a table (6million rows) into another table on
the same instance. The target table has an identity column(PK). What is th
e
fastest way to do this? The instance has to remain up for the web site, and
yes, the target table is read by the web site. I was thinking a bcp out/in.
Thanks,
MichaelUse SET IDENTITY_INSERT ON/OFF to keep the identity column. There's
also a switch in the bcp utility to keep identities (-E)
