Replacing logic board late 2014 to late 2015 - what to do with old SSD blade

[djrounds]

I have purchased from eBay what is purported to be a late 2015 i7 logic board that is supposedly guaranteed by the seller to work in my late 2014 IMac. My original board has the 128GB flash used with the 3 TB fusion drive which was replaced with the OWC SSD kit many years ago. The late 2015 logic board has the socket for the flash but no flash. I'm trying to decide whether to transfer the flash card to the newer logic board and thinking I won't. Any advice on this?

Should be okay, just be aware on sleep wake issues if it’s something you weren’t experiencing on the 2014
