# Had to convert import:: attributes to import_sch config

## What it is

The old schematics import code used board attributes to remember the name of the schematics files and method of import. These attributes had names starting with import::.

The new import code does not use those attributes to store its configuration but uses the configuration subtree plugins/import_sch. The names and meaning of the settings changed too.

This error message is generated once, when you first run import schematics using the new code on a board file that still has the old, attribute based configuration. By the time the error message is printed, the code has already converted the old attributes to the new config.

## What you need to do

Normally: nothing.

There is only one special case: if you plan to use the same board file with older versions of pcb-rnd in parallel to a new version of pcb-rnd and you have to change the import configuration on any version, you will also need to do the same changes on the other version. This is because the new code will change only the import_sch config version, while the old code will change only the attributes.
