1.) Fire Wray while citing that he is going after the deep state. Put the deep state on notice.
2.) Install an acting FBI director that has zero ties to the deep state. Have no intentions of having a confirmed director.
3.) The acting director hires a small secret team of trusted people who will not leak. This team includes IT people and people who know the difference between right and wrong. It's really that simple - no deep state knowledge required.
4.) The team goes after information and documents, but, not in a traditional manner. Every computer system has data that is backed up for disaster recovery. Under the guise of doing a disaster recovery drill for IT systems, recover the data and run those systems off-site where no deep stater will know what is happening. This will avoid tampering and editing of documents/information by deep staters.
5.) Do daily dumps of information, hitting everyone from the janitor to assistant deputies.
6.) Above all, keep the operation legal. Trump needs to personally declassify the information and personally release it in a daily press conference like the ChiCom Flu press briefings. He is the chief executive. He has the power to do so.
6.) Use the same approach at other agencies - grab their data before they can change/destroy the data. Information is power.
I propose we shut down the FBI completely and sell the employees into slavery.
