Cyclone IV GX project failed migration from 20.1 to 23.1std

Hi Jarbugeri,

Sorry I miss your detail in the case description.
From the error "Error: altgx_internal: error renaming "C:/intelfpga_lite/23.1std/quartus/../ip/altera/altera_pcie/altera_pcie_avmm/lib/altpcie_serdes_3cgx_x1d_gen1_08p.v.new" to "C:/intelfpga_lite/23.1std/quartus/../ip/altera/altera_pcie/altera_pcie_avmm/lib/altpcie_serdes_3cgx_x1d_gen1_08p.v": best guess at reason: permission denied"

It seems like your altpcie_serdes_3cgx_x1d_gen1_08p.v.new is somehow missing.
The error can be due to a myriad of reasons and might be difficult to pinpoint exactly. However, I've laid out some suggestions to help we narrow this down further and confirm the error.

1. Try running Quartus Prime as an administrator. Right-click on the Quartus Prime shortcut or executable and select "Run as administrator." This ensures that Quartus Prime has the necessary permissions to perform file operations.
2. Try moving your Quartus project to a location with a shorter path, avoiding spaces or special characters in the directory names. Sometimes, long or complex paths can cause issues with file operations.
3. Copy the file from your previous Quartus version (working) to the one you migrate to.
   

Let me know if this solved your problem.

Regards,
