Merge replication with autoincrement field

Hi guys,
I have two separate system with some data common between them.
For simplicity let's say System A contains some data that is same with
System B. Now I want to get the data from System A to System B by
merge replication (dont want to send data from System B to System A -
using merge replication for filtering using "join". if this can be
done in some other way using transactional replication please let me
know).
But in System A there are few tables with autoincrement fields set for
the primary key field. I am entering data in those tables in System B
also.
Now, how can I handle this - insert records in both system avoiding
clash for the primary key.
PS: I know in MySQL they handle this case by setting up the
replication and then change the seed value and increment value for
different database systems and by thus avoid the clash.
Thanks,
Rakesh.
Rakesh,
on the article properties form there is a tab to manage the identity values.
In SQL 2005 this is set automatically but in SQL 2000 you have to enable it
manually. Once a large range has been selected, there should be no issues as
the ranges are partitioned.
