SyedjahanzaibВ This isВ straightforward to do and you can it remotely. As I am using all Dell servers, I can see the POST & BIOS screens via Dell iDRAC and home lappy screen shows what the screen on the server shows.

The only hard part is how to boot your servers into 'CD' or USB.

#Vsphere client 6.5 baselines inherit update

After the upgrade, you may want to put the ESXi into maintenance mode and run update (Scan for updates, stage patches & remediate) via update manager (since the ESXi can reboot without powered on VMs).

(you may have to go back to step 2 if you unable to store the VMs or power down VMs in both the ESXi 5.0).

#Vsphere client 6.5 baselines inherit upgrade

Reboot the ESXi 5.0 and run the installer, choose upgrade instead of install.this will automatically overwrite ESXi 5.0 into ESXi 6.5.In vCenter 6.5, you should be able to perform vMotion (all VMware licenses now supports vMotion unless 'VMware Essentials').Verify that your vCenter 6.5 have all 5 ESXi hosts (3x ESXi 5.0 & 2x ESXi 6.5)ДЄll you need to know if you have downtime for VMs in ESXi 5.5 (you will need like 30 min, mainly for server to reboot, ESXI install/upgrade takes like 5-10 minutes) ? If no, can the ESXi 6.5 house the VMs (vMotion VMs to the ESXi 6.5 for the meantime) ?Дownload and burn VMware ESXi 6.5 into CDROM and leave them in the ESX 5.0 servers (else you have to create bootable USB drives for each ESXi).Join ESXi to vCenter 6.5 (no downtime needed).Disconnect ESXi to vCenter 5.5 (no downtime needed).I would assume that you have the ESXi 6.x licenses for all the 5 ESXi hosts. There are many 'easy' ways if upgrading ESXi especially when you already have vCenter or the licenses.

Seems like a lot of work but you can squeeze this in one Saturday :) I'v done it, more then 10 times.Дў. Be aware that after upgrading hosts to esxi 6.5 you have to assign new licenses to them. Or, you have option to upgrade ESXI using ssh session to esxi hosts. To perform this steps, after you have upgraded vCenter Server, you can use vsphere update manager in web client to perform esxi upgrade from GUI. You should upgrade to ESXI 5.5 update 3 and then to 6.5. You said you use ESXI 5.0.0, ESXI 5 does not support in-place upgrade to 6.5. After upgrading to vCenter Server 6.5 you will have to assign new licenses to vCenter (you have grace period). I suggest you upgrade to vCenter Server 5.5 Update 3 as first step and then upgrade to 6.5 as second step (between steps you upgrade hosts as well!). Since you are using old vCenter Server version 5, as per Product Interoperability Matrices it is not supported (possible) to perform vCenter Server 5 -> vCenter Server 6.5 in one step. You must not upgrade ESX5.0 hosts managed by vCenter Server 5 before upgrading vCenter Server itself because ESXi 6.5 hosts will disconnect from vCenter Server 5. Before upgrading hosts you have to perform vCenter Server upgrade.

You must check if those ESXi 5.5 servers are on vmware compatibility guide, is ESXi 6.5 supported on that specific server and CPU? (Link to guide: ) If servers you use are compatible with ESXI 6.5 you can proceed forward with planning upgrade, if they are not supported, do not perform upgrade - maybe ESXi 6.5 upgrade will finish OK but you will be running unsupported configuration and you will face problems when VMs power on (if they power on!).Дў.

Here are main things you have to have in mind:ДЎ. Your question was if you could upgrade ESXi 5.0 hosts controlled by vCenter 5 to ESXI 6.5 remotely? Yes, you can perform upgrade remotely but you must do it following right steps.
