Mostly.  Since you're using MailScanner, I presume you also have a bayes database where the spamassassin data is stored.  Per recommended practice, I keep mine in /etc/MailScanner/bayes/ so, as I mentioned below, if you copy over your entire /etc/MailScanner directory before installing (in addition to the /etc/mail/spamassassin directory) the bayes data will come with it.  If your bayes data is located in another location, such as /var/spool/bayes or somewhere like that you'll need to copy that over.

Look in your existing mailscanner.cf file (aka spam.assassin.prefs.conf) and search for bayes_path.  That will tell you where you're storing your bayes (spamassassin data) database.  Be sure to copy it over as well.

Note that I'm using sendmail, hence the /etc/mail directory.  SUSE now defaults to Postfix, so I'm not sure what the directory structure looks like for that.  I'd expect however that the spamassassin directory will be located under whatever it uses in the /etc/ directory.  Perhaps a Postfix user could chime in here if it is much different.
