Clearance transfer from DoD to FBI question

So I recently accepted a new position that is a contractor to the FBI. I currently have a DoD TS clearance and they needed to get the clearance transferred over. I submitted my SF312 from my old job but the new job made me fill out another SF312 to submit along with the usual security briefing form. All of this is in regards to getting a VAR approved for my first day. Is this a part of the process?
