This is automation CI pipeline is core of the G1 to G2 migration process. More details of the progress can be found here.

Migration checklist

• Define date of the workload migration
• Is the project personal or group?
• Are there any data in object store?
• Are there any DNS records on FIPs?
• Do you need to migrate non running VMs?
• Do you need to migrate not-attached openstack volumes? (wording)
• Do you request block of FIPs or random is ok for you?
• To agree on how user gives final migration signoff handshake.

• (required) VALIDATION_SERVER_ID

• (optional) MIGRATE_EXPLICIT_VOLUME_NAMES

Migration steps

• Migrates all running VMs from G1 cloud to G2 OpenStack cloud
  • all related entities are created in G2 OpenStack cloud (keypairs, security groups, volumes, servers, FIP addresses)

• Project volumes which are not attched are by default not migrated.
