Issues with changing to a larger memory CPLD

I have project that I was using 5M570ZT144C5N. I was running out of logic elements and I had to change to 5M1270ZT144C5N. I recompiled with the new CPLD selected and deployed to the target without an issue. However, the project now is using the 5M1270ZT144C5N and does not behave the same when using the 5M570ZT144C5N. What do I need to do to fix this?

Thank You
