DCRUM Upgrade - 12.0.2/3 to 12.2


Hi all,

Just wanted to add a comment on the experience of upgrading to the 12.2 release of DCRUM. 

As mentioned in the title above, the upgrade was from 12.0.2/3 to 12.2. Therefore a straight upgrade with no intermediates. 


  • Small environment consisting of the following components:
    • CAS - With a local DB, CSS, and RUM Console
    • 2 AMDs
    • The Enterprise Portal is not used, and there are no ADS devices

The usual upgrade plan was followed:

  • CSS
  • RUM Console
  • CAS
  • AMD


Whereby all install directories were checked after upgrade to ensure the success. 

When checking the CAS - trying to access the UI from IE8, there seemed to be an issue, whereby the loading of the initial login screen was taking too long. 

When investigating the CAS server log file, it turns out there was a database issue with the CAS, whereby the DB had not successfully upgraded. 

The Fix:  Recreated the schema and kept the last 7 days worth of data. (This was approved by the customer - please do ask before). We then left the CAS to catch-up on the 7 days of data. 

AMD upgrade was successful thereafter, and successful monitoring restored.

I hope that helps - any questions, please dont hesitate to ask.

Kind Regards

Kingsley Hughes-Morgan




Can any one please guide me on how to upgrade CAS from 12.0.3 to 12.4?

Hi Kaushik,

See Upgrade Paths and Migration Guidelines to 12.4. If you want to upgrade from 12.0 to 12.4, the upgrade path is:

  1. Upgrade directly to latest available service pack revision of 12.2 release.
  2. Upgrade from 12.2.x to latest available service pack revision of 12.3 release.
  3. Upgrade from 12.3.x to latest available service pack revision of 12.4 release.
