1.) Currently multi-site can only be configured when system is being deployed from scratch, migration works by renaming the existing Zone/Zonegroups (Z/ZG) to Juju config values on primary site before secondary site pulls the realm data and then rename and configure secondary Zone accordingly. During migration: 2.) If multiple Z/ZG not matching the config values are present at primary site, the leader unit will block and prompt use of 'force-enable-multisite' which renames and configures selected Z/ZG according to multisite config values. 3.) If the site being added as a secondary already contain Buckets, the unit will block and prompt the operator to purge all such Buckets before proceeding.
