Switching between error monitoring tools is generally possible but involves migration effort: exporting your data or configuration from Highlight.io, re-importing or reconfiguring in Datadog APM, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Datadog APM on a non-production project first before migrating.
