Deploy a VMware Integrated OpenStack 4.0 Instance, Backup the Existing, and Migrate Your Management Server Data

To upgrade to VMware Integrated OpenStack 4.0, first deploy a new instance with the latest OVA. You use the new deployment to set up a NFS server and backup your previous management server instance on the new one.

Procedure

1. Deploy a VMware Integrated OpenStack 4.0 instance.

   For detailed instructions, see Installing Integrated OpenStack in the VMware Integrated OpenStack Installation and Configuration Guide.

2. On the new VMware Integrated OpenStack management server, set up an NFS server and copy the SSH key of the previous instance.
   1. Log in to the new VMware Integrated OpenStack management server over SSH.
   2. Run the following command to create a directory for use by the NFS server to store the backup of the previous VMware Integrated OpenStack management server.

      sudo viocli upgrade prepare 3.1_oms_ip /folder_for_nfs_server

      For example: sudo viocli upgrade prepare 192.168.100.101 /data

   3. Enter the password for the viouser account and wait for the operation to finish.
   4. After the operation finishes, keep the console window open.
3. Backup the data from your VMware Integrated OpenStack management server by using the configured NFS server on the new instance.
   1. Open another session to log in to the previous VMware Integrated OpenStack 3.1 management server over SSH.
   2. Backup the data of the previous VMware Integrated OpenStack management server on the new one.

      You can also use the optional verbose parameter.

      sudo viocli backup mgmt_server 4.0_oms_ip:/folder_for_nfs_server

      For example: sudo viocli backup mgmt_server 192.168.100.102:/data –-verbose

4. Migrate the backed up data from your previous VMware Integrated OpenStack management server to the new one.
   1. Return to the console connected to the new VMware Integrated OpenStack management server.
   2. List the contents of the folder created for use by the NFS server.

      For example:

      cd /data
      ll

   3. Copy the name of the directory that begins with vio_ms_.
   4. Reconfigure the new instance by using the folder name from the previous step, the IP address of the new server, and the NSF server folder.

      You can also use the optional verbose parameter.

      sudo viocli upgrade mgmt_server folder_containing_backup 4.0_oms_ip:/folder_for_nfs_server

      For example: sudo viocli upgrade mgmt_server vio_ms_20170918093000 192.168.100.102:/data --verbose

Results

The VMware Integrated OpenStack management server is now upgraded.
