2 Primary servers

[Jeff Kennedy]

What needs to be done to have 2 primary servers running for the same
domain?

I am in the process of moving from one primary to another but want to
test it first and make sure everything works properly, and to see if
the core dump problem of 8.2 on Solaris 2.6 is fixed.  I want to run
the new primary in parallel for a week before making the switch for
real.

Thanks,
