Because vSphere Update Manager is available only with licensed version, you can upgrade ESXi 5.5 free edition to Update 1 with vSphere Management Assistant (vMA).

If no other hypervisors are installed in your network, you can run vMA appliance also from VMware Workstation.

Procedure

Access the host to upgrade with vSphere Client and shutdown all running virtual machines. Right click the VM and select Power > Shut Down Guest. Note the current ESXi 5.5 installed release with build number 1331820.
