Switching from Edexcel to CIE

So this is about maths specifically. A few weeks ago, I posted a question asking whether I can give an AS retest after A2, and apparently, you can't in CIE, but you can in Edexcel. I'm thinking about switching to Edexcel now and wanna know if it would have some sort of drastic impact. I've already done half of my A2 syllabus (P3 and M1).

With a few months left till the actual exams, would it be wise to switch? Is there much difference in the syllabus? I know the paper pattern is different. Also, would it help that I've done Edexcel Maths for IGCSE?

Would appreciate any insights!
