on the flip side, if this is a second remount, the entire creative team is going to want the SM to be up to speed on what was done . . . they may make changes, but they are probably going to have reference the last production (or first production).
The best is to play sort of an archeologist with the paperwork and the video, and spend your pre-production basically recreating the production script to your liking. If you are unclear where a cue went, book the cue, but add a question mark - it may become quite apparent where that cue goes.
But create your script, your production book, everything from scratch - if someone seems upset by that, just say it your's way of learning the show. I have handed over a lot of shows, and watched an ASM rewrite the cues, and one of them just explained, that's the quickest way they learn.
Make it easy for you, and don't worry about offending anyone.
