When you use Phoenix you can convert the CAT files to the ilda format. When you have finish the completely CAT converting, you must build a new story board inside the pangolin soft. It is not possible to convert a completely show. From Pangolin to ilda is it the same thing!

But I thing in a older version of Pangolin, you can convert the completely show to ilda, but Phoenix and LDS have not enough colors for the Pangolin color table.
Only the old file standard of Pangolin (LDA/LDB) without secure blocks can export to ilda.
if everything were so simple. . . . .
