Why weekends? Small moves means you do it during the week and during regular working hours. Done in branches with CI support so that it's pretty unlikely to break anything. If doing regular releases require you to be spending your weekends then you have bigger issues to fix first. Spread it over however long it takes. Why are you trying to make your life more difficult?
I have done this. Regardless of when you do the move everybody who works in the repo being moved is down for several hours at best if you do it during working hours.
