Have a server that runs:

(all GW 8.01)
Primary domain
PO
GWIA
Webaccess

We're migrating to new OES-L server and I'd like to start with GWIA and Webaccess, then move PO later. I'd be creating a new domain on the OES box and installing GWIA/WA brand new.

Question - is this going to mess me up moving the PO later? Or can I migrate PO to the new domain later? Or another approach?

thanks
