Cyclone IV GX project failed migration from 20.1 to 23.1std

Hi,

The error message "altgx_internal: error renaming" you're encountering during the migration of a Quartus project from version 20.1std to version 23.1std suggests that there might be an issue related to the internal workings of the AltGX IP (Intel FPGA IP for transceivers).

Here are some general steps you can take to troubleshoot and address this issue:

• Check Release Notes:
  • Always refer to the release notes and documentation for both Quartus versions. Sometimes, there are changes in the IP cores or project structure between versions, and the release notes may provide information on how to handle such changes.
• IP Core Version Compatibility:
  • Ensure that the AltGX IP core version you are using in your design is compatible with both Quartus versions. Certain IP cores may have specific requirements or updates when migrating to a new Quartus version.
• Re-generate IP Cores:
  • Try regenerating the AltGX IP cores in the Quartus version you are migrating to. This can be done through the MegaWizard Plug-In Manager or Platform Designer (formerly Qsys) depending on your design flow.
• Update Quartus Project Settings:
  • Check and update the project settings and configurations in the new Quartus version. This includes settings related to IP cores, assignments, and other project-specific configurations.
• Review Project Structure:
  • Examine the project directory structure and files to ensure that there are no inconsistencies or conflicts between files generated by the different Quartus versions.

User can normally click on File > New Project Wizard to create a new project with new name in a new folder.

If you would like to create a new project using the existing project, I suppose you must have some small design / RTL that you want to reuse or other reasons. Is the new project related to the old/existing project? If no, you may create a new project with the method mentioned above.

It would be appreciated if you could clarify the purpose of creating a new project by renaming an existing project so that I could provide a suggestion that can achieve your request.
