As above, that's a big jump so will need to be done carefully. We used Ferber at 12months with our twins but they were sleeping in their own cots and were being patted to sleep following a pretty good nap routine and had sleep associations with white noise, a stuffed monkey toy etc. Good luck!
I would highly recommend working with a sleep consultant as going from co sleeping to independent sleeping is a big jump and needs to be done right and involves lots of things like maximising daytime calories, wake windows, layering sleep associations etc x
