I have not upgraded a bunch of these but every one I've tried going from v3 to v4 processor only needed the latest BIOS installed initially for the the upgrade to go smoothly.  My Z440 was a "bare bones" sale and with no processor or memory included.  Bambi knows this...  careful eBay shopping can get some amazing deals and I ended up with an E5-1650 v3 plus 64 GB of the fastest DDR4 memory this motherboard can run because 8GB sticks were too small for some one-percenter.
