My company will be purchasing an equalLogic SAN and virtualizing all of our servers (including upgrading ouur 2000 DC to 2008 ), this will be my first virtualization project. I know that we won't be able to upgrade directly from 2000 to 2008 so I was just wondering where I could find some resources to research this...?...... Specifically I'm curious as to how AD, logon scripts, permissions, etc. will be migrated over. We will actually have a 3rd party assist us with this mnigration but I was just looking for more info to understand this better for myself.
