I'm attempting to build My deck this weekend.I currently have an existing ledgerboard and need to extend it. Would I be able to run the extension lower than the existing ledger and put the floor joists on top of the new ledger
and use hangers on the existing ledger so the decking will be level??

No, you need the joists to butt into the ledger, not sit on top of it, so that the joists won't twist.

Another option would be to not use an attached ledger for the portion that you are extending. Instead, add a girder within 2' of the wall on piers, let the new joists sit on that, and use a rim joist along the house wall that the joists butt into. Extend the girder under the first 2 or 3 existing joists so that you can get the new portion level with the existing.
