Hello.
I would like to know how to use symbols, footprints and 3d models from previous kicad versions(V5) on kicad 7? (my goal is to open an kicad v5 project and ensure to use the kicad symbols from v5)
But i desire to use it on kicad 7, because i want to upgrade totally without the rescue an kicad 5.0.0 project
There are several options.
The most straight forward is to directly add your old symbol libraries to the library tables and them press the Migrate button in the lower right corner. You may have to experiment a bit with that “Legacy” and “Kicad” library format. This makes your libraries available for new projects, but it does not change anything for existing projects. For that you can use: Schematic editor / Tools / Edit Symbol Library Links, or maybe you can put the converted libraries back at the same location and name as the old libraries.
Another option is to first go though the “rescue” process, and then: Schematic Editor / File / Export / Symbols to new Library. If you do this, then at the end KiCad asks you whether you want to: Update symbols in schematic to refer to new library?
You can do this too with footprints on the PCB, but this requires an extra step, because the footprint links in the schematic still point to some old library. You can fix this with PCB Editor / Tools / Update Schematic from PCB (This is the other way around from the normal workflow).
After a project is converted, KiCad leaves some old files around. for example the old [project].pro is not needed anymore because KiCad V7 created and uses the [project].kicad_pro.
