upgrade from 3.5 to 5.5

Hi Experts,
one customer has a very old vmware environment.
All hosts have version esx 3.5.
One host has now errors.

I want to upgrade to latest version of vshere5.5.
Can you tell me the steps, how to upgrade from 3.5 to 5.5 ?
Yet I have just license for 3.5 not 4 or 5  or 5.5.
But I think I can upgrade to the higher version within the evaluation period, right ?

Install another 3.5 ESX host.

Do you have vmotion? If yes then vmotion them to the new ESX and decommision/repair the faulty one.

Else unregister on the old one and register on the new one.

Yes, that is old.

One thing you need to note about ESX 3.5, is it was 32 bit. ESXi 5.5 is 64 bit, and there have been many changes, especially with CPU support, from ESXi 3.5 to 5.5.

So first call, you will need to check the HCL, to see if the server supports ESXi 5.5. (it's unlikely).

Check the VMware Hardware Compatability Lists HCL here

The VMware Hardware Compatibility List is the detailed lists showing actual vendor devices that are either physically tested or are similar to the devices tested by VMware or VMware partners. Items on the list are tested with VMware products and are known to operate correctly.Devices which are not on the list may function, but will not be supported by VMware.

http://www.vmware.com/go/hcl

As for Upgrade path from 3.5 to 5.5, there is not and upgrade path from 3.5 to 5.5.

e.g. you cannot upgrade directly from 3.5 to 5.5.

VMware KB: Installing or upgrading to ESXi 5.5 best practices

The only method would be:-

1. Upgrade 3.5 to 4.1
2. Upgrade 4.1 to 5.5
3. If Server Hardware supports 4.1 and 5.5.

If you do not have any licenses, you can use the 60 Day Evaluation Period, or Register for a FREE License.

But I think you will need to check hardware support. If the host has errors, BACKUP NOW, Export the VMs, so you have at least a copy of them!

Why do you want to install an evaluation version?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Ok this method makes sense.

The only method would be:-

1. Upgrade 3.5 to 4.1
2. Upgrade 4.1 to 5.5
3. If Server Hardware supports 4.1 and 5.5.

I will check the hardware first.
The problem on the host is, there are vm´s on it and it is not possible to migrate them to another. what can I do with these vm´s to go on ?

Move machines to nfs datastore, disconnect from old inventory, reconnect in new inventory, upgrade virtual hardware. Power off old vmware

Hi,

Check hardware compatibility like Andrew stated, and then... If was me?? I will install a fresh ESXi 5.5 in one host, connect to the same datastore and migrate VMs to it.

First you need to have a vCenter running v5.5.

Since I don't like to much upgrades, I always use a fresh install(when is possible). And do upgrade from 3.5 to 4.1 and then to 5.5? It will take all "trash" from 3.5. Clean install will be my first option.

But first check the Hardware compatibility. With that old hw, you need to make sure.
Also you need to bare in mind that now vCenter 5.5 works very different. It as SSO, vSphere Client only works with some feature the rest is in with vSphere Web Client.

Hope this can help

You dont need vcenter. You an connect machine from NFS to ESXi.
Also you may skip immediate purchase in case your hardware is in 5.0 or 5.1 HCL
Why i keep repeating NFS? Because on iSCSI you will need to upgrade filesystem format, so it is worse than NFS

Luciano PatrãoICT Senior Infraestructure Engineer Commented:
Hi,

Always depends on the environment. For using vCenter or even using NFS.

NFS has advantages, but also many disadvantages.

And also should always run out of the 5.1 versions.

and do not at present use 5.5 U1 for NFS it has a Bug!

use 5.5 U0!

gheistCommented:
Yes Andrew, been there too!!!! To work around the bug in 5.5U1 you need VAAI driver for particular storage from HCL (read - expensive storage only)
I assume you meant 5.5U0 with heartbleed patch

vsphere 5.0 introduces storage io control for NFS, that levels out most of NFS shortcomings...

If heartbleed really bothers you!

ESX/ESXi 3.5 is 32 bit.

3.5 was available as ESXi and ESX.

Check the console screen?

Eprs_AdminSystem ArchitectAuthor Commented:
ok I didnt know that esxi was available in version 3.5.
I will check it out thanks a lot for now.

The host is installed on disks with raid1.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Yes, ESX and ESXi have been available since v3.0, up to 4.1. from 5.0 only ESXi.

I have this problem:
You either are not entitled or do not have permissions to download this product.
Check with your My VMware Super User, Procurement Contact or Administrator.

If you recently purchased this product through VMware Store or through a third-party, try downloading later.

gheistCommented:
It means that you dont have active vmware 3.5 support and there is no ESX 3.5 download availble for you.
0
 
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Have you ever purchased VMware ESXi/ESX 3.5?

If not I'm afraid you cannot download it from VMware.

Please note, do not ask any Expert at Expert Exchange for the software, because we are NOT authorised to distribute the software, as we do no have the rights, and it's for this reason it's against EE rules.

I would ask your customer for the media or ask them to login and download from VMware.
