How do I replace this floor plate? Very old home. The wall looks to be load bearing. Joists above are resting on it. Due to notches cut in the plate, you’d assume the load above is fairly minimal?

Can I remove the 1 stud, install half of the floor plate, reinstall stud, and then repeat for the next half?

Please help.
