Hi @Golli1407 @Dhamend,
While I don’t know the exact differences between the two versions, I have to imagine they’re pretty compatible. Worst case scenario, there may be one or two nodes that have since been depreciated in newer Houdini versions, so you will need to replace them and troubleshoot a little. If you do use the newer version and encounter any of these issues, feel free to post them here and tag me and I can help you out.
