Mapping changes while upgrading from PI 7.0 to PI 7.31

Question

Hello Experts,
We are upgrading from PI 7.0 EHP 2 to PI 7.31 SP 14 , Dual stack only.
While migration, there are some doubts related with mapping, which are not getting cleared even from going through various blogs like:
Migration Woes?
PI/XI: PI 7.1 upgrade/migration - Message Mappings
Below are my doubts:
As there are mapping changes for IFS, IFSWITHOUT ELSE & Context functions, so exactly what these changes are and how would this work, how can we identify & rectify in all the mappings?
What changes to be performed for Java mapping & XSLT mapping?
Are there any changes for ABAP proxy?
Any help is appreciated
Many Thanks!!!

Hi Lisin,
You need to change in Java mapping accordingly and compile in jre1.6 as many methods used in older version are obsolete now.
You need to write transform instead of execute which was used for PI 7.0
public void transform(TransformationInput in, TransformationOutput out) 
               throws StreamTransformationException { 
You can easily write the code again in message mapping as discussed:
Write Java Mapping directly in ESR!
For XSLT mapping, the older version will be supported as the execution is done using SAP XML Toolkit which is supported in higher versions also.
XSLT Mapping - Managing Services in the Enterprise Services Repository - SAP Library
ABAP proxy will be as it is if you are going for classical scenario as you will be using 7.31 Dual stack.
But if you want to go for AAE Integrated Configuration, you need to do required configuration changes in ECC for outbound Proxy:
Proxy to file scenario using AAE - with full configuration
I am not sure whether you need to change in Graphical standard mapping for those functions which are already there in PI 7.0.
