Brief background:

We are using SQL Server 2000, and one of the tables stores user
sessions details (each time our users logs into our system we insert a
new record in the session table, and each time user logs out from our
system we insert another record in the same table).
SESSION_ID is the primary key and it is clustered index.
The system produces 5 million session records/day.

The problem:

Each day we transfer the session data (delta only) to other machine and
we want to delete bulk of ~5 million sessions. This should happend
without any interfering of our customers activity ( in the same time,
we should not block the table - new sessions should be created).

What is the best way to perform such task ?
