I am trying to migrate Netware 5.1 sp7 server to new hardware with Netware
6.5 sp5. The source server is located in the DMZ. What is the best way to
setup the destination server as.

I was thinking to put it in the DMZ and allow full traffic to the source
The second option would be to have the second server created in pre
migration mode out of DMZ and just allow full access to the Source server.

Do I have to worry about the ports used in Netware 6.5. Which ports will I
have to have open that are different from Netware 5.1. Which ports are used
during migration and do I have to enable traffic to go through them.

Thank you for your help
