It's another issue. Regarding the update task, we have always used the offline method.

We don't like to login ESXi or vCSA via DNS resolve.

Creating a DNS host just for ESXi and vCSA is a meaningless task.

We really like simply using IP for ESXi and vCSA management. 

In fact, we have used several versions (6.5, 6.7, 7.0.3, 8.0.1) and it's been working for a long time.

Please don't modify this advantage, VMware's engineers.
