After successfully migrating my OpenHAB setup from version 2.5 to 3.0 using a backup file, I was thrilled to see that all my things and items were imported seamlessly. However, my excitement quickly turned to confusion when I realized that none of my DSL rules had carried over. I spent hours poring over forums and documentation, determined to find a solution. Finally, I stumbled upon a helpful guide that walked me through the process of manually converting my old rules to the new syntax. It was a bit daunting at first, but breaking it down step by step made it manageable. I can confidently say that this experience has deepened my understanding of OpenHAB’s rule engine, and I’m now more equipped to handle future updates. If anyone else is facing similar challenges, I highly recommend checking out the official migration guides and community resources—they were invaluable to me!
