Hi This is my first post.
I have inherited an esxi 6.0 host (Del Poweredge R730) with 4 VMs on it. The VMs are servers essential to running the business.
I am planning to update this host to esxi 6.5 this weekend using vCenter update manager. The vcenter update manager documentation (https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.update_manager.doc/GUID-90AA4FDB-B29B-4F7F-A400-38EFC4110024.html) tells me:
"Back up your host configuration before performing an upgrade. If the upgrade fails, you can reinstall the ESXi 5.5.x or ESXi 6.0.x software that you upgraded from, and restore your host configuration. For more information about backing up and restoring your ESXi configuration, see vSphere Upgrade."
I have searched for "vSphere Upgrade." The best I can find is: https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.upgrade.doc/GUID-18B7B4BB-C24A-49CD-AE76-13285157B29F.html but I can't find any information on backing up the configuration.
But we do have full nightly veeam backups of theses VMs and I have successfully done a test restore on to a different host (running esxi 6.5). So I do have a tested workable option if the upgrade fails. But is there something I can do to "backup the esxi configuration" that would make it easier to revert if for some reason I have to?
And to reinstall the old esxi6.0 I asume that means to burn the Dell customized ISO to a DVD and boot the server from it and follow the prompts...? But if I am doing that, whole process, would it not make more sense to just install from the 6.5 DVD. The original install was factory provided by Dell.
I will be doing this on a Sunday. The business is closed and servers can be offline all day if required.
