Transitioning to Application Insights Connection Strings: Essential Insights for Optimizely CMS

Transitioning to Application Insights Connection Strings: Essential Insights for Optimizely CMS

As part of Microsoft's ongoing modernization efforts, Application Insights is transitioning from instrumentation keys to connection strings. While your current implementations using instrumentation keys will continue to operate seamlessly, we strongly recommend updating to connection strings. This ensures alignment with Microsoft's latest standards and maximizes the performance of your Optimizely solutions.

New environments will now be equipped with connection strings by default.

This blog post provides a guide to updating your Optimizely CMS projects, ensuring seamless compatibility with these changes.

Guidance for Optimizely CMS 12 Projects

Existing Projects

  • Promptly update to the latest versions of EPiServer.CloudPlatform.Cms (and EPiServer.CloudPlatform.Commerce, if applicable).
  • Following the update, your next deployment will automatically configure your application to utilize the correct Application Insights connection string.

New Projects

  • Deployments will be restricted unless you are using the updated versions of EPiServer.CloudPlatform.Cms (and EPiServer.CloudPlatform.Commerce, if applicable).
  • Ensure all project dependencies are current before initiating a deployment.

Guidance for Optimizely CMS 11 Projects

Without Custom Application Insights Configuration

  • If there is no custom Application Insights configuration, your next deployment will seamlessly update your application to use the correct connection string.

With Custom Application Insights Configuration

  • Verify that your custom implementation is compatible with connection strings.
  • Reach out to Optimizely support to confirm and deploy the correct configuration for your application.

For more detailed information from Microsoft, please refer to their documentation here.

Can you clarify on the specifics around new projects?

Does this only affect new clients or projects in the PaaS portal, e.g if we use the migration tooling that spins up a new project I assume first deployments will need to be on EPiServer.CloudPlatform.Cms. If we're in the middle of a go live process for a migration however I assume this will be unaffected?
