The 71-year-old is due to hold a press conference launching the book on October 22, which is the same day that Moyes will preview his side's Champions League clash against Real Sociedad.
Despite Ferguson embarking on five tour dates to discuss the book, which is expected to lift the lid on his 26 years in charge, Moyes sees the launch as a positive thing for the club.
"Anything Sir Alex does is good for Manchester United," The Independent quotes Moyes as saying.
"He was an incredible manager. His success was fantastic. I don't see it being negative in any way at all."
United are preparing to take on Sunderland at the Stadium of Light tomorrow.
