Question about mailscanner package updates

[Maarten]

Hello,

I'm redoing my personal mailserver setup and going from CentOS to 
Debian. Now I'm using Ansible to setup everything. I have just finished 
my entire setup and
I just discovered that /etc/MailScanner/conf.d is included for custom 
settings. I don't really want to redo my MailScanner configuration right 
now. So my
question is if mailscanner is updated with an rpm or deb package and you 
then have to run ms-configure --update at what point are updated changes 
made to
MailScanner.conf so that I figure out at what point in my Ansible code 
to make backup of my current configuration so that I can compare the old 
config to
the new config to check if I need to make any Changes to my Ansible 
template of MailScanner.conf?
