Advice in upgrading ESXi 4.0 free to ESXi 5 free
Posted on 2013-01-17
I've done some searching on EE and haven't found my answer to this. Apologies in advance if this has been answered.
I work for a cash conscious SME. I am running a Dell PER 900 using VMware ESXi 4.0 free. This was originally purchased and setup using Hyper-V but, on a recommendation from a colleague I tested VMware ESXi 4.0 and really took to it. The PER900 has an MD1000 Direct Attached Storage unit with the 15 drives partitioned into a number of RAID 5 arrays to support the individual server groups.
We have three production virtual servers running on the host, one of them being SBS 2003 and two servers running Windows 2003 R2 and Windows 2008. There is also a server test environment for a migration to SBS 2011 and a DR network with server copies.
There are also some virtual workstations for RWW users running on the box.
Obviously there are no backup APIs in the free version so I use Backup Exec to backup from within the server structure. This has all worked perfectly ok.
With the release of Windows 8 I discovered that my trusty VMware box would not support the installation.
I would like to upgrade my VMware from ESXi4 to the latest version of ESXi5 but reading the upgrade paperwork just gives me the jitters!
I can find information to upgrade from ESXi 4.1 to 5 but it appears that ESXi 4.0 to 5 is much more of a pain.
Is the upgrade path from 4 to 5 possible to do without ending up chewing your fingers off?
I suppose my big concern is the physical host setup with all the LAN card settings etc. and not being able to back this up at the VMware level.
Can anyone offer any "how to's" on this please?
