I am trying to get a server running CF9 up-to-date by applying all of the available hotfixes listed here:
http://helpx.adobe.com/coldfusion/kb/hot-fixes-coldfusion-9.html
However, I do not know which hotfixes have been applied. The version number being reported by the CFIDE is "9,0,1,274733".
Can I just start at the bottom (oldest first) and just apply all of the hotfixes one by one until they are all accounted for?
You are on ColdFusion 9.01.
ColdFusion 9.0.1: Cumulative hot fix 4 chf4_cf901 03/08/2013
This this the most recent Cumulative hot fix. The also brings in Java 7 support. Note that Java 6, the version shipped with CF 9.x, has been "End of Lifed".
