Mirror updating from 2.7 to 3 ?

Hi ! :)
What is the best way to update silently my enterprise version (600 workstation 2.7 with lan mirror) to the v3 version (with the same options as possible) ?
thx

Thx ! :)
I've tried an silent install over a 2.7 without uninstall on a virtual machine, via the command line \\server\nod32inst\eavbe_nt32_fra.msi /qn /forcerestart /passive ADMINCFG="\\server\nod32inst\options.xml"
I didn't notice any disfonction, but i don't know if it is a good method. In fact, I need to change the deploy and management server too. ;)
