Homekit move home assistant install - rooms issue

I’m in the process of moving my HA configuration to a new installation. As per the homekit component instructions I moved the .homekit.state file to the new installation. All my entities were successfully transferred to the new installation.

My problem is that the rooms I had created in the old installation were not moved to the new installation.

Is there a way to transfer the rooms to the new installation also, so I dont have to manually recreate them?

Thanks
