Home Assistant instance in Synology VMM and Docker in parallel

Hi, want to change from Synology docker installation to Synology VMM in order to get supervisor core version etc. What I did was backing up docker version, installing VMM and creating a copy of docker version by restoring the backup.
For a interim period I am running now both instances in parallel to check if VMM HA instance covers all my docker HA instance functionality. So far everything works perfectly. But I wanted to be sure that a parallel run of two Home Assistant instances attaching the same device network would not lead to any serious problem. Any hint? Thanks a lot!

Perfectly fine for most integrations

If you use something like zwavejs (addon not docker container install) where a usb device is being controlled directly by HA there will be an issue with the single integration. In this case you should limit the integration to one install
