I think the easiest way to handle such custom modifications is to re-download the old 1.9.4 archive, compare the files to your current installation (e.g. using diff on linux webserver), upgrade, and then re-apply the changes.The same way you can compare the 1.9.4 and 1.9.5.x versions and see what changes have been made.The download links ;)http://osticket.com/sites/default/files/download/osTicket-v1.9.4.ziphttp://osticket.com/sites/default/files/download/osTicket-v1.9.5.ziphttp://osticket.com/sites/default/files/download/osTicket-v1.9.5.1.zip
