How do I upgrade my server running ESXi 4.1 to 5.1? Is this straightforward as downloading the 5.1 image and boot my server with it? It will not wipe the content?
Hello,
You can upgrade using a ISO via DVD in sever without problem. It´s very easy, but you cannot have virtual machine in localdisk . Check too if your vcenter already running in v5.0 to support manage this server.
This can help vSphere Upgrade Guide
have this unofficial link but can help too http://blog.vmpros.nl/2011/07/13/vmware-easy-upgrade-esxi-4-1-to-esxi-5-0/

good luck
I'm not sure i agree with the post above...
I had an ESXi 4.1 server in my test lab with virtual machines on local storage. I booted from the CD, chose to upgrade with the option of keeping the existing VMFS partitions and the upgrade completed without a hitch. All virtual machines and data in my pre-existing VMFS were retained...
Depending of method he need change virtual machines allocated in local datastore (Safety). If you´ll upgrade with CD you don´t have any problem. But before ugprade double check what option you chose. :smileygrin:
Villa what you say is correct .
Works fine!! Excelent.
Motherboard: Intel S3420GPLX, 16GB RAM, 2TB SATA disk.
IRMM 3 (Intel® Remote Management Module) = video, keyboard, mouse, usb, iso...
Source VMware ESXI 4.1.
Update to VMware 5.x with all Linux and Windows Virtual Machines, all ok.
After update my hypervisor server remotely I update VMware Tools with no error.
Thanks everybody.
