I have an existing project in Eagle 5.12. I'd like to convert it to KiCad 5.0.2 (this is the latest I downloaded today).
I have tried using the KiCad File/Import Project. It failed. I suspect it wants Eagle 6.0 or later, but I have found no concrete list of what Eagle versions are supported.
I found an Eagle ULP named eagle2kicad.ulp designed for Eagle 5.8. I tried running that, but it only did the schematic, and failed with many errors. The resulting schematic was completely unusable. I suspect this ULP was written for an earlier version of KiCad.
What do I need to do to convert a Eagle 5.12 project (both board and schematic, including all library symbols, etc...) to KiCad 5.0.2?
