Is it necessary to run ALL scheduled processes after a CWB or upgrade install?

Summary:

Currently, our team that supports recruitment runs a number of scheduled processes after every P2T (we run a handful of one-time jobs and prepare a number of continuous scheduled jobs). We are wondering if it is necessary to do the same after every CWB/quarterly upgrade install.

I can understand running the one-time processes (and perhaps a couple of scheduled processes that are related to those one-time processes), but if the other scheduled jobs are already running, is it necessary to stop the old schedules and re-schedule them after a CWB and/or quarterly upgrade?
