I have a question about Progress Openedge licensing:
- Install Openedge RDBMS on a single "Microsoft Hyper-V" virtual machine, 
does it require you to purchase Openedge Replication?

Microsoft Hyper-V would be running on 2 physical machines
for resource sharing purposes such as storage.

However, the virtual machine with Openedge RDBMS is one,
with no disaster plan required for the database.
