  • Virtuozzo 6.0


Attention: Use the instructions from this article if you want to perform a major upgrade of the Parallels Business Automation - Standard (PBA-S) server operating system (OS), e.g. an upgrade from CentOS 3.x/4.x to CentOS 5.x or CentOS 6.x. In this case, you need to migrate PBA-S to the new server.

If you want to perform a minor update of the PBA-S server OS within the current major release (e.g. if you want to update Centos 6.x to the latest version), use the instructions in this article: How to update OS (minor) of PBA-S server.

You can use the following instructions to migrate the PBA-S system from an old container/server into the new one based on the new OS distribution:

  • Important: If the destination container is located on another Hardware Node, the new PBA-S license for the new HWID should be requested in advance of the migration. Please refer to this article to determine the HWID of the new Virtuozzo Hardware Node.

  • Upgrade PBA-S system on the source node to the latest version.

  • Install the PBA-S system on the destination node with a more recent OS distribution installed. The identical PBA-S version (the latest one) should be installed. Please refer to the Parallels Business Automation - Standard Release Notes and the Parallels Business Automation - Standard Installation Guide for detailed instructions. In addition, you should assign a temporary IP address to the destination PBA-S server/container (TMP_IP for further reference).

  • Refer to the article How to accelerate hspc-mn-backup utility on accelerating the hspc-mn-backup utility.

  • Migrate your system to the new сontainer/server using the hspc-mn-backup utility on the source node:

    ~# hspc-mn-backup -m root@[TMP_IP]

    IMPORTANT: Use the option -d if you migrate from CentOS 5.x to CentOS 6.x or Redhat 5.x to Redhat 6.x:

    ~# hspc-mn-backup -d -m root@[TMP_IP]
  • Stop the source node (shut down the PBA-S server or stop the PBA-S container).

  • Change the IP address of the destination server/сontainer to the source IP address.

  • Start the PBA-S system on the destination node/container.

  • Install the new PBA-S license if the new container is running on a new Hardware Node.

Additional Information

The same instructions may be used if the PBA-S database is located on an external server. Use the following scheme for migrating PBA-S from CentOS 5.x to CentOS 6.x (Redhat 5.x to Redhat 6.x) and an external database from CentOS 5.x to CentOS 6.x (Redhat 5.x to Redhat 6.x):

  1. Upgrade PBA-S 4.3 CentOS 5 to PBA-S 4.5 CentOS 5.
  2. Set up a new PBA-S 4.5 CentOS 6, 64-bit, and migrate from PBA-S 4.5 CentOS5, 32-bit, with hspc-mn-backup according to the above instructions.
  3. Set up a new DB server with CentOS6 and MySQL 5.1.66-2.
  4. Migrate ALL databases from the old DB server to the new server with mysql/mysqldump.
  5. Verify that the new DB server has the same IP address as the old server. Configure settings in /etc/hspc/hspc.conf if the new IP is different. Make sure that a connection to MySQL from the PBA-S node is possible.

For additional information regarding hspc-mn-backup utility usage, refer to Parallels Business Automation - Standard Advanced Configuration Manual.

Ensure that the OS distribution installed on the destination node is listed on the Requirements tab of the PBA-S Resources page.
