FCE and Other Errors

Pretty new to the world of mikrotik. So forgive me if some of these questions are obvious.

We recently upgraded from an RB 1100 w/ 50/50 ethernet. To a CCr 1200 with full fiber.

I upgraded firmware on 1100 and exported the config to the CCR. It seems to be working fine but I am getting a lot of FCS errors and/or the nic’s keep going up and down.

Never had this problem before and was wondering if there is something I missed in the switchover.
