Good day everyone,
I am new to VMware and have been tasked with upgrading my company's VMware infrasturcture to v5.1
Presently our vSphere consists of:
- vCenter 4.1
- 64 bit physical server
- SQL Server 2008
- 64 bit physical server
- 10 ESX hosts running 4.1
I've been reviewing the document the vSphere Upgrade Guide and based on the procedure outined, approach is as follows:
- Upgrade vCenter
- Upgrade Update Manager
- Upgrade ESX hosts
- Upgrade datastores to VMFS version 5
The upgrade of vCenter seems straight forward enough.
However, I have questions about upgrading the ESX hosts. I hope to use Update Manager to upgrade the hosts and they provide a warning to backup the hosts, but I haven't found any documentation about backing up the hosts.
Any assitance, advice, suggestions will be greatly appreciated.
Thank you.
