We're in the process of upgrading the ESX 3.5 environment to ESXi 4.1U1.
Is the upgrade path from ESX classic to ESXi with VUM supported?
If so; is while installing / upgrading the hosts with VUM attached fiber channel still an issue? The installation docs of 4.1 still mention the detachment of fiber when installing manually.
To way to upgrade a ESX to ESXi.
The only way is a reinstallation.
