SideFX offers a one time conversion of the Apprentice/Indie files and HDAs.

To qualify for this conversion you must have just purchased a perpetual Houdini FX or Houdini Core license. A short term rental of a commercial Houdini license does not qualify for this conversion offer. The conversion is valid only at the time of your first purchase of this full commercial Houdini license.

Email support@sidefx.com to check the eligibility of the conversion.

Please make sure to package all the .hiplc (or .hipnc) and .hdalc (or .hdanc) files you need converted.
Create a zip/tar archive and upload to your support files. As this is a one time conversion offer, make sure to package everything.
