You will most likely need to upgrade to 200 amp service, install all new wiring from the crawlspace or attic, install all new boxes - way more than are in each room now, patch in all the old ones, install all new switches, etc, etc. Major renovation = major $$$.

Much easier and more cost effective to just move and let someone else deal with the updating.

Or, upgrade the service to 200 amp and install new power outlets as needed and leave existing stuff alone.
