running the upgrade_MailScanner script

[Gioia Bastioni]

I have a 4.23-11 MailScanner version installed on /etc/mailscanner
I would like to upgrade to 4.24-5, installing the new version on /opt/MailScanner.
What happen if I run the 'upgrade.MailScanner.conf' script included on the new distribution of MS ?
I mean am I right doing the following:

[TAR ditribution]

cd /opt/MailScanner.new/etc
../bin/upgrade_MailScanner_conf /etc/MailScanner/etc/MailScanner.conf /opt/MailScanner.new/etc/MailScanner.conf > MailScanner.new
mv MailScanner.conf MailScanner.old
mv MailScanner.new  MailScanner.conf

thanks
