Migrating from Stand-alone Z2M + Z2M Proxy to HA-integrated Z2M

[GarryG]

Hi,
I initially had Z2M installed as a container on a Raspberry, with my HomeAssistant running off-site on a more capable machine. At some point, I got a better local box with decent performance, and moved HA to it as a VM. I kept the rest as was (apart from moving the containers to another VM on the new box).
I was wondering, how much of a problem is it to migrate Z2M into the HA install? Is this doable without requiring to re-learn all the devices? (not too many, albeit still a hassle to go around the house and re-do everything, including naming in Z2M etc.)

Thanks!
