Hello World,
We have one very old Java application written in Jdk 1.3. We want to upgrade that application to Java 7.
Does this migration process will be manual (try – error – fix) sort of process or is there any tool available which can tell me upfront what are the code changes needed, what are the dependencies needs to be upgraded etc.
If there is any such tool please let me know.
Thanks in advance.

No tool that I know of that will do this for you.

I suggest you start by considering whether you need to upgrade code which is working correctly.

Since JDK1.3 there have been two new keywords (enum and assert); if you have used either of those as an identifier the code won't compile.
