The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

ESXi 3.5 to vSphere ESX upgrade - best practices?

Asked by jimlahey in VMware

We've recently purchased vSphere 4.0 and some new hardware. What is my best bet for upgrading easily/quickly?

Our current configuration is 1 ESXi 3.5 Host w/ 5 VM's, all located on our SAN and connected via iSCSI. We've also purchased a new server for load balancing and fault tolerance.

So here is my main query: Would it be easier to just install ESX 4.0 onto our new server, import the VM's off the datastore/san, and then clean install 4.0 over our current 3.5; or would using the vCenter Host Update Utility be the way to go? From the documentation i've found, i only see ESXi to ESXi and ESX to ESX upgrades via that tool. Am I mistaken?

If I could just upgrade our current 3.5 ESXi to 4.0 ESX that would be ideal, as we have our current server and SAN, but are not expecting the new server hardware for a few weeks.

Note I have a vCenter license for 4.0, but am just using VM Infrastructure Client 2.5 to connect to our current 3.5 ESXi. I've noticed that I cannot use the newest version (4.0) of vSphere client to connect to our ESXi server, it prompts and then installs 2.5
Thanks!
