Cloud upgrade 9.2 to 9.4

Hi, we are on the cloud and plan to upgrade our environment from v9.2 - v9.4. I have a couple of questions in blue regarding the upgrade.

 

  • .NET 10
    • ASP NetCore & Desktop Runtime
      • Who handles the installation for the web and app servers?
      • Do we need to install these in our Gateway servers?
  • Upgrade Request
    • When submitting the request to upgrade from 9.2 - 9.4, how quickly does the change happen?
      • We’d like to minimize any system downtime and coordinate with our IT team to install .NET10 in our gateway server (if needed) + upgrade the Smart Integration Connector 
  • Desktop Client

I am currently compiling business rules and comparing marketplace solutions compatibility. Do let me know if there are other areas I should look out for!

.NET10

Upgrade Request

  • Submit a case to support, they will be able to provide more details on the timing of upgrading from 9.2 to 9.4 based off of your application.

Desktop Client

  • The ClickOnce install you are currently utilizing will automatically kick off a 9.4 client install once the SaaS infrastructure has been upgraded and your users access the URL.
  • Installing the MSI/EXE is also supported if needed.
  • Note that the right client version will be needed for the environment, the desktop client is not backward or forward compatible across 9.x releases.  For instance, if you have a non-production environment that you upgrade first, your users will need to use the 9.4 client for that environment and the 9.2 client for your current production.  The ClickOnce install method will work in that scenario as well, but your users might see the install happen more often when switching between environments.
  • Additional resource for Solution Compatibility: https://documentation.onestream.com/docs/Content/Solution_Compatibility/Solution_Compatibility.html
  • While not specifically for upgrading from 9.2 - 9.4, there are some overlaps in relation to the .NET 8 to .NET 10  in the following post: 

     

Thanks
