Upgrade from vcenter6.7 to vcenter6.7U1,Esxi6.7 to Esxi6.7U1
1. Download the vcenter upgrade package in the format: VMware-vCenter-Server-Appliance-6.7.0.20000-10244745-patch-FP.iso. It is impossible to upgrade with the original VMware vCenter Server 6.7U1. Download address: https://my.vmware.com/group/vmware/patch#search
After the 2.vcenter upgrade, upgrade the underlying Esxi, import the Esxi6.7u1.iso image file in vcenter, and then create an upgrade benchmark.
3. During the upgrade process, the virtual machine on the host will be moved to another host, and after entering the maintenance mode, the upgrade will begin, and then the OK will be automatically restarted.
4. "disk format conversion" is suggested in the upgraded vsan health status. It is recommended to shut down all virtual machines except vcenter. It was previously judged that data loss may occur. After this test, the conversion is smooth and fast, or there may not be a lot of data for the time being. Probably the principle process is to remove each disk group and then reassemble it, so it involves data migration. When the quantity is large, I think the speed may be a little slow.
