Simo, on a side note - I am thinking, would it make sense to create a new
command "ipa migrate-ipa" which would migrate data from other IPA installation?
I.e. it would migrate users, groups, hosts, sudo, hbac, automount, etc?

I came across several user cases where creating a replica was not an option and
migration like this would have been beneficial.
