Upgrading to StruxureWare Data Center Operation version 7.5 from version 7.3.x or 7.4.x takes at least 10 minutes (however depending on size of your solution). An upgrade of the Webmin module is needed when upgrading. You must have a valid service contract to be able to download this version from the server download page. It is recommended that you perform a backup of the data on the Data Center Operation server before initializing the upgrade.


If you have modular PDUs in your setup and run a version prior to v7.4, download and use the Webmin plugin described here before you upgrade.


If you run an External system integration through ETL, see ETL - Extract Transform Load before you upgrade.

Red Hat based DCO server

You cannot install the upgrade package. Instead take a backup of version 7.4.5 of the DCO server, do a clean installation of version 7.5, and restore the backup.

These instructions take you through the upgrade in a cluster environment. If you are upgrading a single StruxureWare Data Center Operation installation, simply ignore the instructions about additional nodes and follow the rest of the instructions.

If you are upgrading a cluster environment, the StruxureWare Data Center Operation upgrade only needs to be performed on one node. The upgrade scripts apply the upgrade to all the cluster nodes.

If you have a disaster recovery node, you will have to upgrade that after upgrading the cluster.
If you upgrade in a cluster environment, the upgrade takes up to about 20 minutes.

If you have a disaster recovery node running, upgrade the disaster recovery node like upgrading a stand-alone server (Steps 1+2 below).


  • Back up the data on the Data Center Operation server.

  • Uploading the upgrade file through Webmin requires a browser supporting file upload sizes over 2GB, such as:
    • Chrome, version 8 or higher (Windows, Mac OS X, Linux)
    • Safari, version 5 or higher (Windows, Mac OS X)
    • Opera, version 11 or higher (Windows, Mac OS X, Linux)
  • If you are upgrading a cluster environment, you must ensure all cluster nodes run and can access the upgrade file before beginning the upgrade.
  • If you are upgrading a cluster environment from version 7.3.0, run the sudoers upgrade file script before beginning the upgrade.
  1. Download the upgrade file and copy the MD5 key from a location provided by the support team.
