Upgrade Hyperflex ESXI from 6 U3 to 6.5 U2

[mzoair]

Hi everone,

i am new to hyperflex, i did my first deployment two days ago using the latest HX installer 3.01e and ucs version 3.2.3h and the same for B & C series and vcenter 6.5 U2. i didn't upgrade the ESXI version before cluster creation so it is still 6 U3 so now i need to upgrade the 3 hosts (HX240c M5)to 6.5 U2 and i wonder if the below procedures is the right one. please guide me if something is missing

1- download the 6.5 u2 offline bundle and copy to all esxi host

2- put the first host in HX maintenance mode

3- upgrade the host using the offline bundle and reboot

4- repeat for the remaining servers

appreciate your feedback and comments

Above steps looks good. Few pointers i want to add:

1. Use only customer HX ESXi image- hopefully you are aware of it (https://software.cisco.com/download/home/286319572/type/286312290/release/6.5.U2 )

2. Makes sure cluster should become healthy before you move to another Esxi upgrade.

Let me know if that help.
