Hello: Looking at what it will take to upgrade to GW 2012. The biggest obstacle I face is that we will be keeping our Netware 6.5 server running BorderManager. This same server also hosts a secondary domain containing are GWIA gateway. All other GW pieces live of OES2 sp3 servers in our primary domain.

So what I need to determine is: Can I upgrade our Primary domain (postoffices, mta, webaccess) while leaving the secondary domain alone, and will the primary domain still work with the mta and gwia on the Netware server? Anyone do this? What gotchas may pop up?

Thanks, Chris.
