Ikea Dirigera HomeKit backup

I’ve recently moved form Raspberry Pi 3 to Hasos running on Proxmox.
As the backup and restore to the new installation did not work (took forever, also this process is not easily debugable) I decided to start almost from scratch.
I managed to move ZHA network to new device.
However there is a problem with pairing again with Ikea Dirigera HUB (I know I can move all devices to HA Zigbee but for now I want to stay on Dirigera)

Few months ago when I set up the HUB it appeared in Devices as Homekit Device then I think I had to do some “pairing”. Now the new installation of HA does not any HomeKit Devices.
Maybe there where some changes in Ikea’s firmware and the Smart Home App or maybe the HUB is paired with the old HA on Raspberry and can only be used once?

Is there some way to manually(not using backup which clearly does not work) copy the config files form Raspberry Pi HA to the new Proxmox HA ?
