• Upgrade existing MS to 4.2. This MS will become region 1
• Disable all the zones in region 1
• Dump region 1 DB
  • mysqldump -u cloud -p -h <region1_db_host> cloud  > region1.sql
• Install 4.2 MS in the remaining Regions
  • Set the region_id while installing the DB
  • cloud-setup-databases cloud:<dbpassword>@localhost --deploy-as=root:<password> -e <encryption_type> -m <management_server_key> -k <database_key> -r <region_id>
• Copy region 1 DB to other regions
  • mysql -u cloud -p -h <region2_db_host> cloud < region1.sql
• In each Region, delete all zones from the DB which are not supposed to be in that region using zone delete script. e.g if zone 2 is moved to region2, it has to be deleted from region1 using the script
• Start all management servers. At this point all regions contain only the desired zones
• Enable zones in the required regions
• Destroy CPVM and SSVM in each zone, so that they will be recreated

Limitation:Zone migration currently does not support zones with KVM hosts
