Ad 2003 upgrade

Posted on 2012-09-18

We have a single forest/domain with 3 DCs running AD 2003 with Win 2003 32 bit servers.
We want to upgrade the domain to Ad 2008 running win 2008 R2 64 bit servers.
We would like to replace the existing DC hardware with new servers but keep the existing server names.
The FSMO roles are split between 2 dcs.
What is the best strategy for this?
Do we update the schema first then add win 2008 servers or vice versa?

    are all DCs in same site?
    if so, I will update the schema, transfer the FSMO to 2 DCs. De promo the one that has no role.
    remove it from the domain, dc promo the 2008 dc with the removed name.
    transfer the role to the 2008 dc and do the rest of de promo and promo.

    Do I need to  introduce a Win 2008 DC into the domain before I upgrade the schema and domain?
