I have read the release notes and searched the forums.

I am running version 6 open source on Ubuntu 10.04 LTS

I want to upgrade in-place to version 8 running Ubuntu 12.04 LTS

I see that 10.04 is supported but deprecated and there are 2 different Ubuntu installs.

Can I upgrade in this order?:

1. Download and run zcs-8.0.6_GA_5922.UBUNTU10_64.20131203103719.tgz
2. Upgrade Ubuntu to 12.04

My main concern is whether Zimbra for Ubuntu 10 will keep running once Ubuntu is upgraded to 12.
