Temporary Virtual Server for Application Upgrade

Hello,

I have an application that I will be upgrading soon. The upgrade is going to be an "in-place" upgrade of the application and will take about 2 weeks. Therefore, the application will not be available during the upgrade process. To get around this issue, I would like to create a virtual host using a spare server I have, and P2V the current server with the application over to the host and then take the server being upgraded offline for upgrading. This way, I will have the existing server and application in virtual form and the application still available to our users while the existing application server and application is being upgraded. Once the upgrade is complete, I would take the virtual host offline and return users to using the original server and now upgraded application. I have attached a diagram of my intention for clarity.

My question is, would I be able to do this using existing free VMware products such as Esxi? And if so, what tool would I use to P2V the server?

Thank you in advance,
Jason

You could just switch to the virtual environment forever....

But, yes you can use VMware ESXi for FREE.

see my EE Article, Step by Step Tutorial Instructions with Screenshots (also applicable for ESXi 5.5)


Part 1: HOW TO: Install and Configure VMware vSphere Hypervisor 5.1 (ESXi 5.1)

Part 2: HOW TO: Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client

and to create the P2V, you can use VMware Converter also for FREE....

more of my EE Articles to help you...

HOW TO:  P2V, V2V for FREE - VMware vCenter Converter Standalone 5.5

HOW TO: FAQ VMware P2V Troubleshooting

Have a think about what you want to do....

because once you have P2Ved the server to a virtual environment....and then let you users use it, you could create a clone of this server, and with it practice upgrading this version before "touching the physical" or remain virtual.

Remember, you cannot have the same IP Address and Computer Name on the network at the same time....

So with your current plan....you will have to make IP Address and Names changes...
