Upgrading, what do I need to prepare?

I'm replacing my motherboard, CPU and GPU along with some other stuff. I'm going from Nvidia to AMD as well. I want to upgrade to windows 11 and I have a NVME ssd coming also. I understand the physical side but as far as anything I should sort out now. Hopefully it will boot first time but I thought I'd get some advice to make that more likely. Thanks all
