I am going to be upgrading and migrating from
Release 6.0.8_GA_2661.UBUNTU8_64 UBUNTU8_64 NETWORK edition.
to a vmware UBUNTU 10.04-TLS 64 bit running ZCS 7.

During my UBUNTU 10.04 install I want to make my /opt partition on another ISCSI SAN block.

Should I create my new server and then install 6.0.14 and then migrate my users, or will I have to upgrade my 6.0.8 to 6.0.14 on my production server first? If this is the case would it be better to upgrade the production server ZCS 7 off the bat?

This is my first experience with Zimbra.
Thank you in advance for any suggestions or help you can supply.
