You mean switch a system, live, from CentOS to SL or to our upsteam
vendor's release?

It's tricky, but doable. The hard parts are the tools that include
"/etc/redhat-release", which must be force replaced, getting the yum
configuration set up  for the switches, and replacing *everything*.
Replacing yum, python, and glibc components are particularly fragile,
since doing s "downgrade" to go to the older operating systems's
releases can be..... adventuresome.

Dude, no. You do it *LIVE* to switch a system.. Since the SSH daemon
forks off copies of itself, to allow a restart of the daemon with the
existing connection intact, it's feasible and I've done it.

But given the availablity of cheap, large USB sticks these days, why
wouldn't you have a local bootable installation medium?
