Can the ADS8 board be used to support AD9081-FMC-EBZ in any circumstances?

My customer wishes to evaluate the AD9177.

All documentation say that to evaluate this part the AD9081-FMCA-EBZ is the correct evaluation board to evaluate AD9177.  Understood. The documentation for the AD9081-FMCA-EBZ cites that the ADS9 is mandatory.

My customer has an ADS8 FPGA board & asserts that he has been told that the ADS8 board can be used if 'upgraded'.  Please can you confirm if that is correct & what is necessary to do that.
