you have several options. If you have vCenter and Update Manager you can import this ISO file and create new baseline. Attach it to this ESXi host and remediate. Of course this vCenter cannot run on host being updated.
Second option is to upload image to datastore, connect to host using putty, move host to maintenance mode and utilize 'esxcli software profile update' command.

Ok then I was on track as I first check the cli -option. So basically I am on right track here...
I have HP proliant and current ESXi SW is following:

~ # vmware -vl
VMware ESXi 5.5.0 build-2403361
VMware ESXi 5.5.0 Update 2

I have downloaded and uploaded in to datastorage with winscp.

1. I need to put host to maintenance mode either through vpshere or commands

2. esxcli software sources profile list -d /vmfs/volumes/datastore1/

HPE-ESXi-6.5.0-OS-Release-650.  Hewlett Packard Enterprise  PartnerSupported

3. Then I run the update:
esxcli  software profile update -p HPE-ESXi-6.5.0-OS-Release-650. -d vmfs/volumes/datastore1/

4. Wait it to be successfull and then put the maintenance mode off

5. Check the current SW with esxcli system version get

This first try does not have vcenter or any VM's currently running on it. So now it goes like this. But other hosts then have vcenter and/or vm's also...

So this basically is it?

Yes, it is it. Before you update to ESXi 6.5 you may also check that your server is on VMware HCL list.
It is also wise to update all firmwares like BIOS, controller fw, etc before you perform ESXi upgrade.
