> Reference: the Mapping Model at https://cwiki.apache.org/confluence/display/CLOUDSTACK/Mapping+model+for+CloudStack+zone+and+Vmware+datacenter
> Considering a model where a CloudStack deployment will have some zones with multiple
DCs and some zones with single DC. This comes from the fact that existing CloudStack deployment
has zones with multiple DCs. But after upgrade to the newest version, customer would like
to have existing zones to operate as-is. But all new CloudStack zones would be having single
DC. In this model, the existing zone with multiple DCs is termed as Legacy zone and it will
not support the zone wide features are requires a zone to have only 1 DC. Also operations
on legacy zone should be seamless (like adding a cluster etc.) as they were before upgrade.
This means the code base doesn't apply any new logic, that affects the functionality, over
legacy zone. For example, constraint checks that happen while adding a cluster to new zone
should not be done if the zone is legacy zone.
