Upgrading KiCad 4.07 to Kicad 5 missing all symbols

remap ALL R, C, and Ls. Then I will tackle the ICs.

After remap, if you have issue with the library names you can either use KiCad tool for update and each symbol to link to the correct lib again, or you can export the schematic into csv BOM which symbol lib info. Then you can to fix using excel software to work on CSV BOM file, and run my script below:

Back import custom fields

I just public this bom_plugins/bom2sch.py from here, it may help you to backport value if the custom fields already defined in your schematic; {EDITED} python bom2csv.py XXX YYY Where input file XXX can be root .sch file, or .xml file. YYY is a output csv file name python bom2sch.py YYY [XXX] Where output file XXX can be root .sch file. YYY is a input csv file name.
