Swapping Blades on S9 miners

[Darthswan]

Evening,

I have two s9 miners.  One has socket connection fail, connection refused issues and the other one's blades are slowly dying.  Had a power failure and the middle blade died, and now the next blade is starting to go.  They are batch 13 and batch 20.  Can I take the blades from one and stick them in the other with no problems.  The batch 20 machine is the one having the socket connection fail issues. 

Thanks in advance.
