I prefer to do [build|install]world prior to building the kernel
with the new installed tools.

Even with an outsynced system, the most common tools to be affected
are ps and top.  Even when a kernel fails to boot all the
way through, you can still rebuild a new kernel after booting
with the old kernel.  Having the new system tools will not
hurt.

The OP's primary goal was to discuss about if it was possible
to upgrade 5.x to 6.x remotely via ssh.  I provided that it
was possible and what my method is.
