How To Upgrade ESXi 5.5 to update 1,2,3...

today im trying to upgrade my esxi server, from 5.5 to 5.5 update 1,2 and 3

steps :

download the update from :
https://www.vmware.com/patchmgr/findPatch.portal

after that  : copy downloaded files into datastore
note* if you try to make new folder in the datastore, better without any space or other simbols.

then.. we go to SSH an login as root
- do check before, so we can check later if our esx upgraded or not, using the build number.
how to check ?   -- > type vmware -v in ur console

\

now we try to find the upgrade files in our datastore .

after we find it.. do the installation with esxcli command.

esxcli software vib install -d /vmfs/volumes/52f25d31-555e3b54-4de6-40f2e9248bc2/UPDATE-ESXI-5.5/update-from-esxi5.5-5.5_update03.zip

the format is

 esxcli software vib install -d ( /vmvs/volumes/datastorename/zip file location )

and when done, you need to restart your server. In this case im trying to upgrade to update 1,2,3 so i dont do restart every upgrading. 

just install update 1,2 and 3.. then i do restart.. ( im not finding any error / effect ).

like this picture below.

now we check, if it upgraded or not by sync it with the build version from the web

vmware build version

                          Version                                                                    Release date  Build number

finally my esxi upgraded...

cheers...
