    Did you review the explanation in Quartus help?

    CAUSE: The specified I/O has a memory interface specific sub-block, but is not associated with a DQ_GROUP or MEMORY_INTERFACE_DATA_PIN_GROUP. To ensure that these sub-blocks get placed, the corresponding I/Os must be associated with a DQ_GROUP or MEMORY_INTERFACE_DATA_PIN_GROUP.

    ACTION: Add memory interface grouping assignments to the specified I/Os. In most cases, this can be done by running Tcl Scripts generated by the ALTMEMPHY MegaWizard.

    It's not clear whether you regenerated the IP either. You can't just move IP from one device to another without regenerating it for the new device because of the different resources available.
