Welcome to the Hubitat community!
I believe this is possibly the reason Bobby suggested you signup for the beta program.
If you still have your Home Assistant installation running, you can use the best of both worlds by using the community built Home Assistant Device Bridge. This would allow you to keep your existing Zigbee bulbs paired with Home Assistant, and use them in Hubitat for automation and other applications. Many of us (myself included) run both Hubitat and Home Assistant. I prefer the ease of use and power of Basic Rules and Rule Machine on Hubitat Elevation, while being able to also enjoy the massive library of compatible Zigbee devices via Zigbee2MQTT running on Home Assistant.
