Doesn't matter as lon as the link is where it should:-).

Sort of. You should run the upgrade script from the new install,
supplying the old MailScanner.conf as the old file, and the new
MailScanner.conf file as the "rpmnew" one:-). I *think* the upgrade
script will instruct you correctly if you run it without an argument.
It needs the new "default" file so that it can tell what options to
remove/add from the old one. It will print the new and improved
version on standard output, so just redirect that to a file
MailScanner.new, look through that one, so that it looks OK, then move
it into place on the new install.

Yep.

Eh, all it means is that you need use whatever startup script to stop
MailScanner, do "rm /opt/MailScanner" to remove the symbolic link to
the old install, "ln -s /appl/ms4.69.3 /opt/MailScanner" to create the
symbolic link to the new install... and then use the same startup
script to actually start it running again.

Hope that clears any confusion:-)
