There are two ways to migrate data from Insomnia to Insomnium.
  1. In Insomnia, use the GUI button Export files from the "Insomnia" Project under Perference/Data to export files (e.g. to your ~/Downloads).

    After that, open Insomnium and import these files using the Import to the "Insomnium" Project button under its Perference/Data.
