Noting that it's now possible to modify the CA certificate

at install time in 4.5 and 4.6, is there any provision for doing so
after an upgrade to one of those releases with a cert that originated in
a 4.4 instance? Possibly involving renewal of the (externally signed)
CA cert, if necessary?
I'm not authoritative on this but I don't think so.
Using an external CA would probably the only way this would work but
even then I have my doubts. Some other things would also need to change
like the LDAP certificate profile(s), existing certs would probably need
to be re-issued (I'm particularly fuzzy on this part b/c while the
issuers wouldn't match the CA private key would) and maybe some other
corner cases.
It would be an interesting exercise if you wanted to give it a go on
some test system(s).
