Upgrade ESXi 3.5 to 4.1 summary:
- upgrade ESXi 3.5 to 4.0 Update 1
- upgrade ESXi 4.0 Update 1 to 4.1
- I cannot upgrade EXSi 3.5 to 4.1 directly using Host Update Utility
Upgrade procedure:
- Download “VMware vSphere Client and Host Update Utility 4.0 Update 1”. (VMware vSphere Client 4.1 download package does not include Host Update Utility)
- Install VMware vSphere Client and Host Update Utility 4.0 Update 1.
- Download “Upgrade package from ESXi Server 3.5 to ESXi Server 4.0 Update 1” ZIP package.
- Launch Host Update Utility 4.0 to upgrade ESXi Server 3.5 to 4.0 Update 1 with the ZIP package. This will upgrade ESXi to 4.0.0 build-208167.
- Then follow the instruction on “Upgrade vSphere ESXi from 4.0 to 4.1 Using vihostupdate”
What a confusing nightmare of documentation and various update files VM has created. I followed you quick steps but unfortunately the Host Update Utility says that it does not support updating my ESXi 3.5 lone host even though their own documentation says this is possible.
ReplyDeleteTotally lost.
@Glen:
ReplyDeleteyes it says that they can not be patched but "host update" button is available.
