    Upgrading to DCO 8.x from previous versions

    Data Center Operation end of version announcement

    DCO 8.3.x, its modules, and all prior versions on January 1, 2022. More...

    The latest version of DCO is available to customers with a valid Software Support contract. 
    To verify your contract and receive the latest download links, please fill out this form.

    To upgrade to the latest version of 8.x, use one of these methods:

    • Backing up a previous version and restoring it on a new clean 8.x installation
      You can use this for upgrading from any DCO versions 8.x and 7.x.

    • Upgrading using the latest 8.x iso file
      You can use this for upgrading if your current version of DCO is at least 8.0.
    From version Upgrade path
    8.x Upgrade or backup/restore
    7.x Backup/restore
    Older than 7.0.0

    Backup/restore

    Note: You must restore your backup on a 7.x server first before you can restore it on 8.x.

    Backing up a previous version and restoring it on a new clean DCO 8.x installation

    You must have internet access to upgrade to 8.3.2 from 8.x.

    This upgrade method includes taking a backup of the data on your old DCO, making a clean installation of DCO 8.x, and then restoring the data in the new DCO installation.

    If your previous version is older than version 7.0.0, you'll need to restore your backup on a 7.x server first before you can restore it on 8.x.

    First, remember to back up your solution so you can restore the backup after installing Data Center Operation on the new server. Otherwise, the installation will wipe all current data. You will lose all data if you skip creating the backup.

    A new installation of Data Center Operation 8.x is required, preferably on a new dedicated server. You can then transfer all your data (data center model, user settings, historical data, and licenses) without loss using the backup and restore procedure.

    Recommendation

    Install DCO 8.x on a new server and keep the old DCO version running concurrently on the old server until you have verified that your new DCO 8.x server is up and running.

    Installing Data Center Operation on the existing server is not recommended. If you choose this approach, be sure to create an external backup file before beginning the new installation process (e.g. save to a share or download the backup). See more here.

    Saving a backup from the existing Data Center Operation server

    For DCO 8.0.x to 8.2.7

    1. Open the Webmin web interface in a browser by typing the address of your Data Center Operation server in a Web browser followed by :10000, https://<hostname>:10000 - e.g.: https://192.168.1.100:10000 .  
    2. Log into Webmin and in the left menu, select StruxureWare DC Operation.
    3. In the submenu, select Backup, and optionally type a comment for the backup.
    4. Click Backup now. You have now created a backup in a local backup directory (/data/backup) on the server.
    5. Download the backup from the server by selecting StruxureWare DC Operation>Restore, selecting the backup you want to download, and clicking Download selected backup. This file is the one you will later upload to your newly installed DCO 8.x server.

    For DCO 8.2.12 to 8.3.x

    1. Open the web client by typing the address of your Data Center Operation server in a Web browser, https://<hostname> - e.g.: https://192.168.1.100 .  
    2. Log into web client, select Administration>Backup and Restore.
    3. In the submenu, select SCHEDULE BACKUP, and optionally type a comment for the backup.
    4. Click OK. You have now created a backup in a local backup directory (/data/backup) on the server.
    5. Download the backup from the server/web client by selecting Administration>Backup and Restore, selecting the backup you want to download, and clicking Download. This file is the one you will later upload to your newly installed DCO 8.x server.


    Setting up a new server with a clean installation of Data Center Operation (such as 8.3.2)

    See the entire installation process here.

    Copying the backup file to the new server

    1. Open the web client by typing the address of your Data Center Operation server in a Web browser, https://<hostname>
    2. Log into web client, select Administration>Backup and Restore.
    3. Click the UPLOAD BACKUP tab.
    4. Browse to the location of your saved backup file.
      Make sure the file format is: <name><yyyy-mm-dd><hh.mm>.tar.gz

    Restoring the backup file on the new server

    1. In web client for the new server on which you want to restore the backup.
    2. select Administration>Backup and Restore.
    3. Select an uploaded backup file and click Restore.
      If the backup you want to restore is not in the list, upload the file.

    Upgrading using the latest 8.x iso file

    Upgrading to Data Center Operation version 8.x takes at least 10 minutes (depending on the size of your solution). Perform a backup of the data on the Data Center Operation server before initializing the upgrade. 

    Note: You can upgrade a Red Hat based DCO server from version 8.0 to the latest 8.x versions. For versions older than 8.0, use the backup/restore method to get to the latest version.

    The upgrade takes up to about 20 minutes. You should not try to access or use Data Center Operation during the upgrade.

    Prerequisites

    • Make sure you back up the data on the existing Data Center Operation server to a remote location.

    • Uploading the .iso 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)

       

    1. Download the .iso file from a location provided by the support team and copy the SHA256 key from the same location.
      To locate the telephone number for the support you need, visit Contact Us.

    2. Upgrade Data Center Operation.

      1. In the Webmin left menu, select StruxureWare DC Operation>Upgrade.
      2. In Select upgrade file, browse to the location of the downloaded StruxureWare Data Center Operation .iso file.
         If you upload the .iso file to the StruxureWare Data Center Operation server without using the Webmin interface, place it in the /data folder.
      3. Copy the SHA256 key and paste it into the field.
      4. If your setup requires it, select the non-obligatory fields, No thirdparty RPMs* and Do not download packages from the Internet.
        - Selecting to not include 3rd party files may be relevant if you are running on Red Hat and your company policies force you to install those packages separately. *Do not select this option as the upgrade will fail! Instead, if your setup requires this option, create a post in the community requesting help with the upgrade and our team will get in touch with you.
        - Selecting not to download from the Internet may be relevant if you know you don't have an Internet connection during the upgrade as it may be a bit quicker when the upgrade doesn't check for newer files online.
      5. Click Upgrade.

    3. When you have completed the upgrade, you can launch the web client and download the latest version of the Data Center Operation desktop client.

      1. On the computer on which to install the Data Center Operation client, open a Web browser and launch to the IP address or hostname of the DCO server <serverIPaddress> to log in to the web client and get access to the desktop client download.
        (The DCO web client is automatically available with the server installation.)
      2. If you're not an English speaker, select your preferred language from the profile menu Language option (profile image in the upper right corner).
      3. In Administration>Licenses add your license keys to enable download according to your purchased licenses.
      4. In the profile menu select Download Desktop Clients.
      5. On the download page click to download the Data Center Operation software according to your license and follow the instructions in the installation wizard.
      6. Repeat the above steps on all desktop client computers.

    Logging in to the new version of DCO after upgrading

    Log in to the DCO web client interface with your usual credentials. From the web client, in your profile menu, you can select to download desktop clients.

    Licenses and local DCO users will be restored as part of the backup. AD users are handled in AD.

    All users with a password shorter than 6 characters must change their passwords. 

    For security reasons, it is recommended that you create a new DCO administration user with a complete set of user rights, including user administration rights, and then delete the default apc/apc user, or at the very least that you change the password of the apc user.

    After making sure that the data was successfully restored, you can decommission the old server.
