Show and Unlock everything on all stories to make sure that everything is movable.
Surround, and be generous, the entire project with the multistory marquee. Check every story that the marquee encompasses everything.
. Zoom out so both the project and global origin are both visible in the plan window and then drag everything in the marquee close to the global origin.
And, just to be safe, make a copy of the file first, so if something gets missed or messed up you have a backup of the file at the point before you do this.
