hard drive - Repairing Windows EFI after moving a partition

I have two HDDs, the first one has a EFI partition and a windows partition, the second one has no partitions.

I want to move the windows partition to the middle of the second HDD, and boot from it. Most likely I will have to repair the EFI (BCD) after that.

My questions are:

1. "Can I" / "Do I need to" "move" / "clone" the EFI partition to the new HDD as well?


2. Do I need to remove the windows installation from the first HDD to repair the second one or can I have both working?



3. Assuming that:

   
   
   
   
   1. I can copy the windows partition with gparted (cylinder alignment) and possibly the EFI as well,
   
   
   2. I have a recovery USB stick ready, and
   
   
   3. I have a backup done,
   
   
   
   

   is there any hole in this plan that will screw my computer completely?
