When upgrading to a new UPD (Update) version, the CORE layer code cannot be merely replaced. Consideration has to be taken on how the UPD will affect the code in the CUST layer. IFS Update Analyzer is used to identify the changes that need to be performed on the CUST layer in order to upgrade to a new UPD.
The input for the analyze is a set of folders. You must point out where the files for your existing solution is based upon, and which update version you are targeting at. Furthermore, you need to tell where all you customized code is stored.
All customized code are scanned and analyzed in order to identify where actions need to be taken before the upgrade.
