Migrating from one hub to another

[sunlighten]

Hello,

I’m transitioning from Smartthings to Homseer. I recently purchased a Hometroller G3 Pi to test and see if my devices pair and work correctly before I take the plunge. Since adding all my devices is time-consuming, I’m wondering if there’s a way for this Mac, non-programmer newbie to transfer all of hus rooms and devices from one HomeTroller to another, or if I decide later, to a larger Plus or Pro?

Also, is there a way to save a backup file on my local computer to restore later?

Thanks
