If I was going to pack it to move it outside the house, I’d remove the drives first. Put the drives back in before powering. I think I read that the drives do not need to be in the same order, but I’d still do it.
I move mine fairly regularly- disks out - and in these convenient cases.
That might be overkill for a one time move. I like those cases because I backup to bare drives in an external dock. I have a growing pile of bare drives that deserve better protection than those anti-static bags.
Do a good proper power down with a safe removal and reinstall the drives before powering up. You never want to remove or reinsert good drives with the power on. That might make the Drobo think the drive failed, or at best it’s tempting fate.
