PDMLink 9.1 and 10 on the same test machine?

[ssmith-6]

Is it possible to have PDMLink 9.1 and 10.0 both running on the same server, just for a test installation of both?

Can they share any of the components, such as the directory server for example?

Yes, you can have test installations of both on the same server and they
can easily share a WindchillDS installation.

You can use VMWare or another virtualization software and have as many Windchill installations as your storage system allows.

Or there is something that prevents you from using virtualization?
