Upgradation of BIRT 2.2.1 to BIIRT 2.32

Hi,

We have used BIRT for the reporting and it used BIRT runtime 2.2.1.The build scripts uses maven

But now we need to use the latest version of BIRT runtime as the older version has the issues with the db connectionleakage. As a part of it, we have updated the local repository with the BIRt runtime 2.3.2. And changed versions of the jars of birt in the pom.xml But the maven build was failing. Should we have to do anything else?

And incase if it is successfully built, will the 2.2.1 code work with 2.3.2?
