Consolidating two Organizations

[quinla01]

Any advice on this one would be great.

I need to start thinking about consolidating two organisations. Organisation “A” currently uses a public address range. Organization “B” uses a private 192.168 address range. Both networks are at 2003 functional level.

We have a dedicated line between the two organizations. The overall aim is to decommission organisation “B” domain and get all resources over to organization “A” domain.

I’ve heard there could be problems with this since one of the networks is on a private address. I’ve heard something about replication between the two domains wouldn’t work since one is natted.

Thanks guys.

If you've got VPN links or routers with a ptp link between sites, as long as your machines on each domain know how to route packets from one site to the other, this should be possible using ADMT, USMT, and (if necessary) ExMerge. Create a trust between sites, and migrate users via ADMT, migrate their profiles via USMT, and migrate Exchange data via ExMerge.
