Install Domino Server 6.5 & 8.5 on the same machine

Hi All,

I have already installed on Domino 6.5 server and Notes Client (Desinger, Administrator, etc). Now due to some new requirement I have to Install Server 8.5.x as well as Notes Client 8.5.x

I want to know that is it possible to install both the server as well as client on the same machine with same platform. If so kindly let me know How?

Thanks

Regards

Ashish
