Issue/Introduction

SDDC Pre-check failed before upgrading vCenter/NSX/ESXi to the latest version 

"A VM faults were found while performancing a dry run enter in maintenance mode validation"

Cause

Edge VMs cannot migrate to other hosts due to an EVC issue, which leads the ESXi to be unable to enter maintenance mode.
