Migration from megawizard to qsys ip

First of all I need to be able to edit the project. It is not just a simple copy-paste. Second I also need to migrate from SOPC to QSYS: The architecture changed from having a processor->PCIe->FPGA to a SOC device so qsys is mandatory.

I got an error complaining about a setting in a dual port ram(CIII) that is not supported in Cyclone V. With the old megawizard you could just open the dualportram.vhd file, edit it if necessary and save targeting the new device. With ip catalog this is not possible any more (should not be to hard because it is still megawizard...). Since the old ip core files are just *.vhd they don't appear in any ip-core list. No automatic upgrade option available.
