Upgrade ESX 3.01 to 3.5, some simple questions.

[Frans_P]

Hi everyone,

We currently have 12 ESX servers which are running version 3.01 and Virtual Center version 2. We now want to test Windows 2008 and i run into a lot of problems using version 3.01 as the host so i'm thinking about upgrading everything.

A few simple questions:

- Do you all recommend upgrading? Or should i do a clean install?

- Does Virtual Center needs to be upgraded to version 2.5 first?

- If upgrading from 3.01 to 3.5 is an option; will all the attached storage volumes stay untouched and will the VM's be able to launch on 3.01 aswell as on 3.5?

Best Regards and many thanks in advance.

• Do you all recommend upgrading? Or should i do a clean install?

I prefer clean install - however upgrade is an option. If possible, do the clean install.

• Does Virtual Center needs to be upgraded to version 2.5 first?

Yes ESX 3.5 is only supported with VC 2.5 - VC 2.5 Update 1

• If upgrading from 3.01 to 3.5 is an option; will all the attached storage volumes stay untouched and will the VM's be able to launch on 3.01 aswell as on 3.5?

Yes

I also recommend upgrading your license server.

All the best.

Some other questions:

- Will ESX 3.5 also change things in the current VM's?

- Will VMotion be possible between 3.01 hosts and 3.5?

Thanks for your quick reply!

• Will ESX 3.5 also change things in the current VM's?

• --> you can/should install VMware tools and this changes the VM

• Will VMotion be possible between 3.01 hosts and 3.5?

• --> yes its possible

Kind regards

But as I understand it (correct me if I'm wrong), all hosts should be at 3.5 Update 1 before updating VMWare tools. I never really got a good explaaination for this other than "do it that way".
