Hmmm....
Well, I have a primary DNS server that's our web server also.
The zimbra server is on a different server, and when I originally set that up, I used
Split DNS - Zimbra :: Wiki . So my zimbra server is ALREADY a secondary DNS server.
The reason I ask if I can run multiple instances is because, this existing 5.0.16 server is on a dual quad cpu with 8GB memory, which is definitely over kill for our company. So to setup a third independent server with 6.0.1 for testing: 1. would I setup a third split DNS, possible? 2. or could I just run multiple instances of zimbra on the existing server? And how would I change all the ports? 3. How would I install 6.0.1 along side/parallel to 5.0.16? ./install.sh -s ?
Thanks!
