I am working in a project where omniture tracking is implemented and it works fine without any issues. We have a new requirement in project that states, we need to replace the existing library file s_code.js(Version H22) with the new s_code.js(VersionH26) This library file has been provided by our adobe consultant.
I am being asked to find out the impact of this upgraded file on our project. Depending on the impact we need to decide whether we should accept this requirement or not.
For testing purpose I already replaced s_code.js with a new version in my local system. I checked for javascript errors. Everything seems to be good.
Posted this question just to make sure, if there is anything I need to verify specifically apart from javascript errors.
If you really want to, you can go through the release notes to find out what has changed from H22 to H26, but there shouldn't be any issues or things to consider from the upgrade. Mostly it has been some refactoring of the core code to make it more efficient, though there have been some additions and changes that enable you to take advantage of newer reporting capabilities and some other stuff for tracking (which is kind of irrelevant if you aren't planning on changing your implementation).
Sidnote: I kind of wonder why you're second guessing your Adobe Consultant, in the first place though.. is it an Adobe ClientCare rep, or is it some 3rd party consultant? If it's the latter, perhaps this is an indication to find a new consultant!
