Check whether your hosts is compatible for ESXi 5.5. You can check vmware compatibility list on vmware site.
1. Download ESXi 5.5 iso
2. Plan a downtime. Power off your vms
3. Boot your host with esxi 5.5 iso (Take remote console through ilo/idrac or mount a CD physically to the host )
4. Once you accept the EULA, you will get list of options, here choose "Upgrade ESXi, preserve VMFS datastores"
Wait for upgrade to complete.
Thanks
