This could lead to the old cronserver running, but new webserver running. If they're being run from different directories, this would cause problems, e.g. as the cronserver and webserver communicate with each other through the DB, and they would be using different DBs.

I wonder if there's some way we can have a cronserver die when its corresponding webserver is killed? There isn't really much point in having the cronserver running by itself anyway...

What do you think: Probably safest, for now, to just leave the old cronserver running? Especially since it may be desirable to have two or more servers running in parallel on the same system.
