Convert а component library .eli from 3.1 to 3.0 version

[Tre]

I updated my libraries under version 3.1 and now on another computer these libraries do not work where version 3.0 is installed because the file format .eli has changed in version 3.1.
How to fast convert a component library .eli from version 3.1 to version 3.0 or later?
It is possible only through the export/import DipTrace ASCII file?

If you don't want to update DipTrace 3.0 to 3.1 you can export libraries to DipTrace ASCII format from DipTrace 3.1. Then import ASCII files in DipTrace 3.0.
