vCenter Migration from 5.5 to 6.5

Hi All,

I would like to gather information on which is the best way to migrate vCenter Windows 5.5 to VCSA 6.5.

Our challenge is that the setup is using dvswitch 5.5.

And I saw a KB that migrating dvswitch from a new version may result downtime that,s why we are trying to minimize or much better eliminate that concern especially this is production environment.

Upgrade a vSphere Distributed Switch to a Later Version

Will using vCenter migration tool automatically upgrades the dvswitch version from 5.5 to 6.5?
