This makes sense,  I've upgraded hosts in the past and separation makes this easier.

Why not push most of this to PAAS ?   The learning curve is pretty small,  you can still
run a non-authoritive bind secondary locally, or  use imapsync to maintain a copy of all your
email locally for backup, but you avoid all the hassle of upgrades.


For nesting - yes even though there are published ways to make this work,  my point is this
isn't likely supported,  so your on your own for any issues.   For instance on
ESXi you must turn on promiscuous mode on the network segment (port group) the nested hypervisor
connects to.  This causes all sorts of extra network/cpu - so again for a test or
training environment that's ok but not the best for production.
