If you have both Indie and Education, you can flip between the licenses.

To launch Indie using an Indie license:

houdini --skip-license-modes=commercial,education,apprentice

or

hindie --skip-license-modes=commercial,education,apprentice

To launch Education using an Education license:

houdini --skip-license-modes=commercial,indie,apprentice

You can also add an environment variables to your houdini.env:

HOUDINI_INDIE_LIC_OPT="--skip-license-modes=commercial,education,apprentice"
HOUDINI_LIC_OPT="--skip-license-modes=commercial,indie,apprentice"
HOUDINI_FX_OPT="--skip-license-modes=commercial,indie,apprentice"

What that will do is any time Indie is launched, or hindie is called, it will always use the Indie license. Whenever the main Houdini FX application is launched (houdini or houdinifx command) is called, the Education license will be used.
