Upgrade to SCOM 2012 R2: Unable to proceed

The upgrade time has truly come!

During an upgrade at a costumer site I got the following error when trying to upgrade the secondary management server:

Unable to Proceed

Setup could not detect the current Data Warehouse Scenario. Please ensure that the SQL Server service for the Data Warehouse is running, and the current user has permission to access the Data Warehouse.

I checked the services and I had already upgraded the RMS emulator server so i was sure it wasn’t a permission issue.

Time to dig a little deeper…

And sure enough! The DataWarehouseDBName and DataWarehouseDBServerName were both empty:

Pretty fixable – I simply put in the database and server name:

I crank up the installer again and this time SCOM isn’t complaining:

Happy upgrading to SCOM 2012 R2 – see you on the bright side
