Have you tested we need to do this?

I believe this won't be as easy, because we need to change the id column as well. Now we would assume, that the same host_id is referencing to the facet_table, but that is not the case.
Here is proposed (pseudo = untested) code:

Suggested change

	def change
	HostConfigGroups.where(:host_type => 'Host::Managed/Base').update_all(:host_type => 'ForemanPuppetEnc::HostFacet')
	def up
	group_ids = HostConfigGroups.where(host_type: %w[Host::Base Host::Managed]).pluck(:config_group_id, :host_id)
	group_ids = group_ids.each_with_object(Hash.new([])) {|(cfg_id, host_id), memo| memo[host_id] += [cfg_id] }
	group_ids.each do |host_id, cfg_ids| do
	facet = ForemanPuppetEnc::HostFacet.create(host_id: host_id)
	HostConfigGroups.where(host_type: %w[Host::Base Host::Managed], host_id: host_id).update_all(host_type: 'ForemanPuppetEnc::HostFacet', host_id: facet.id)
	end
	end
