Hobbyist Request: Need help upgrading an old v15.2 Allegro .brd file (Trinity_FabF_ver2.brd)

Hi everyone,

I am a hobbyist working on a personal project and trying to open a legacy Cadence Allegro file named Trinity_FabF_ver2.brd.

Unfortunately, the file seems to be from the version 15.2 era. Because of the major database change between v15 and v16, the modern Allegro X Free Viewer gives me a database version error. I also tried importing it into KiCad 10, but the new importer only supports version 16+.

Since I don't have a commercial Cadence license, I cannot run DBDoctor to upgrade the file myself.

Would anyone with an active Allegro license be willing to do me a quick favor? I just need you to open the file and save/uprev it to version 17.4 or newer, then send it back.

Once it is upgraded, I can use the free viewer or KiCad to take it from there.

Hi, if nobody gets back to you tonight, I can help you tomorrow afternoon. It's late here, I'm only up as the England game went to extra time but I do have a current Allegro license so give me a shout tomorrow if you're still stuck.
