Re: [isabelle] Transfer Isabelle2011 Code to Isabelle2014
Have you tried doing this port yet, so that you can report specific things that have been causing you problems? I can imagine many proofs that would go through unaltered.
There are no scripts for porting from one version to another.
I find it useful to run both the old and the new copies of Isabelle during porting. Then you can see where a proof goes wrong. Then the simplest thing is to see whether sledgehammer (greatly improved since 2011) can solve the problematical case.
Try to rewrite some of your proofs in the structured style. That gives you control over variable names and makes future porting much easier.
