Getting my Zimbra NE Server (7.1.3_GA_3346) updated to Zimbra 8 seems to be a bit of work. I would just like to confirm that I do have it right, so please tell me if I am doing it right, or if there is a better way doing it.

Questions: (I am running a 140user stand-alone server)
1. Is CentOS 6 the best way to go? (I am running on CentOS 5)
2. Should I consider the Appliance? (I am running on a ESXi Server)

Steps I think I need to go through to get to Zimbra 8: (Please correct me if I am wrong!)
1. Create a new Centos 6 Server.
2. Install Zimbra (7.1.3_GA_3346) and follow steps from Platform and OS Independent ZCS to ZCS Migration Using Rsync - Zimbra :: Wiki

Any help/ assistance would be greatly appreciated. I was hoping I could migrate to Centos and Zimbra 8 without having to install Zimbra 7...

Kind regards
