Maintenance on 2 node VSAN

Hi, are there any guides on how to perform maintenance on a Branch Office VSAN (2-node + witness)? What Maintenance Mode options are available and recommended, Ensure availability or Full Data Migration?

Kind Regards

Good morning, with the 2 node config there is only ensure availability.  In fact that is the only option for a 3 node config as well, there is nowhere to migrate the data to.  In order to do a full data migration you need at least 4 nodes.

It should be noted that should the witness become unavailable in a 2 or 3 node config while it is in maintenance, the VM will become unavailable.

Thank you, Zach.
