Hi Augustus,I'd suggest to take a look at the following thread where I described the upgrade pretty well:http://forum.osticket.com/d/discussion//resolved-upgrade-to-latest-release#latestAnd yes you can go from 1.6 ST directly to 1.9.12 (current latest stable version). The package can be downloaded here: http://osticket.com/downloadIf you experience any difficulties or problems, let us know ;)Cheers,Michael
