If my server is at 9.0.1 with no hot fixes and I want to get to 9.0.1 up to date with the latest hotfixes up to apsb13-27. Do I install the cumulative hotfix 4 for coldfusion-901 as described in http://helpx.adobe.com/coldfusion/kb/cumulative-hotfix-4-coldfusion-901.html and then install apsb13-27 (update 11) as described in http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb13-27.html?
I don't need to install cumulative hotfix 1, 2 & 3 first; right? Cummulative hotfix 4 includes 1, 2 & 3; right?
One other question, from people that have done this type of upgrade...is it pretty safe? I plan to test pretty thoroughly on dev before doing the same on prod, but I was wondering if others have seen very many issues when doing this?
With apsb13-27 use section 2 for 9.0.1.
You would also do well to apply apsb13-19.
CHF4 includes 1 2 3.
After CHF4 + apsb13-19 + apsb13-27 you will have these JARs in ColdFusion9\lib\updates
After CHF4 you might like to be aware this implements a new setting in ColdFusion, Post Parameter Limit. Read more about that here:
