For customers who wish to upgrade from Gliffy to draw.io, or who want to run both add-ons temporarily or permanently, draw.io comes with a practical feature: Gliffy mass import. All diagrams created with Gliffy can be quickly and easily imported into draw.io, and edited as if they were native draw.io diagrams.
