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.
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).

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
-dif 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.
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):
- Upgrade PBA-S 4.3 CentOS 5 to PBA-S 4.5 CentOS 5.
- 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-backupaccording to the above instructions.
- Set up a new DB server with CentOS6 and MySQL 5.1.66-2.
- Migrate ALL databases from the old DB server to the new server with
- Verify that the new DB server has the same IP address as the old server. Configure settings in
/etc/hspc/hspc.confif the new IP is different. Make sure that a connection to MySQL from the PBA-S node is possible.
