Virtual Connect Server profile management

[kwg]

Hi there folks,  I primarily work with Cisco UCS so forgive me for thsis basic question, but since its so basic it should be really easy for someone to answer and move me on my way..  

We just built out an older c7000 chassis and virtual connect, and in doing so I'm struggling to see how it is I can update a server profile with a new VLAN and have it propogate to all blades that use that profile.   I say this because now that I have a profile built, it appears that the only way to apply this profile to more than 1 blade is to copy it and then apply the copy to the device bay.   But after I do this to all the blades, can I update the profile with a new VLAN and have it automatically applied to all the blades?

can I update the profile with a new VLAN?

Yes but before apply must be backup running configuration.

And have it automatically applied to all the blades?   

No you must be use copy or apply one by one.
