Programming

Agreed.

We need to see their code. We cannot predict, or even fix anything without that.

Its unfortunate that I cant share the code/logs here since it is against our company's policy. Thank you all, It was a good learning and I was able to convince my seniors about the redundancy of this task.

C++ is a huge and multi-paradigm language. Rewriting an interpreted language with an compiled language has the potential to be faster or more efficient in terms of the final machine code read by the CPU. However, creating efficient code in C++, similar to C, is hard. If you do not have much experience with coding and reasonable paradigms used in the language, I would strongly discourage you to use it. Think about a higher level language that would be easier to debug/code or something you're more familiar with.
In case you are a decent C++ programmer, you should only rewrite programs in a low level language like C or C++ if you really need to get all the bits of performance possible out of it (like 3d game engines, which I write in C++). Else, it isn't necessary, and will only be a pain in the neck.
When looking at your situation, I would personally first try to rewrite/fix the code in perl itself, before moving to any other language.
