The latest version of DCO, if needed, is available to customers with an active software support contract.
Customers who are currently running a release which is older than DCO 8.3.x should first plan to upgrade to DCO 8.3.2 or newer. In this case, two new servers are required.
To upgrade to IT Advisor, customers may use this method:
-
Backing up their DCO 8.3.x and restoring it on a new clean ITA installation.
Note: When you upgrade DCO 8.3.x to ITA, your Colo, High Availability, and Insight licenses are stripped out during the upgrade. See Differences between DCO and ITA

Backing up DCO 8.3.x and restoring it on a clean ITA installation
Upgrading to IT Advisor 9.1.x or newer requires a clean installation of ITA and a restore of the DCO 8.3.x backup file.
This upgrade method includes taking a backup of the data on your DCO 8.3.x server, making a clean installation of IT Advisor, and then restoring the backup file in the new ITA installation. This is the required process for customers upgrading to ITA 9.1.0 or newer.
NOTE: This procedure assumes you are installing IT Advisor on a new physical server or virtual machine. If you perform a fresh installation of IT Advisor on the same DCO server, then all existing DCO data/information will be lost if the DCO backup was not copied from the server.
Recommendation
Install IT Advisor on a new server and keep the DCO 8.3.x running concurrently on the old server until you have verified that your new ITA server is up and running.
Saving a backup from the existing Data Center Operation 8.3.x server
