The website message is aimed at RealWorld users who are concerned about upgrading. According to the message, "The most common reason people call us to upgrade is due to system crashes." It also reports most callers are not performing regular backups. Passport notes it can help with a smooth transition and safe data migration and "with the click of a button, your new software can look just like the RealWorld screen." One reseller site says RealWorld had 15,000 to 20,000 users when purchased so it would be interesting to know how many have remained loyal.
