Upgrade to v0.88 from earlier versions of SigNoz

Important: Dot Metrics Migration Required

SigNoz v0.88 introduces a migration from normalized, underscore-based metric names (e.g., system_memory_usage) to unnormalized, dot-based metric names (e.g., system.memory.usage).

This change aligns with OpenTelemetry semantic conventions and enables better namespacing and cross-signal compatibility.

For more details about this migration, see this guide.

Before or as part of upgrading to v0.88, you must migrate your existing alerts and dashboards to use the new dot-metrics format. Failing to do so may result in broken dashboards or alerts.

Please follow the Dot Metrics Migration Guide for detailed instructions and requirements.
