VisiCore’s Cribl Migration Checklist: From On-Prem to Cribl Cloud Managed

Migrating from on-prem to a managed Cribl Cloud deployment empowers your business to scale faster, cut operational costs, and strengthen compliance. With a clear roadmap and proven best practices, your team can unlock the full value of Cribl while staying focused on driving insights and innovation.

1. Pre-Migration Planning

  • Create Data Inventory – Audit current on-prem environment:
    • Sources (syslog, API, collectors, etc.)
    • Destinations (SIEMs, storage, observability tools)
    • Pipelines, routes, and packs in use
    • Worker groups, nodes, and load balancers
  • Identify a migration project team (Cribl admins, DevOps, networking, security, and business stakeholders).
  • Document compliance, encryption, and data sovereignty requirements.
  • Identify dependencies (proxies, firewalls, TLS certs, Redis/state tracking, NFS).

2. Platform Evaluation & Readiness

  • Compare feature differences between on-prem and Cribl Cloud (scaling, security, observability).
  • Decide deployment model: Full Cloud (Cribl Cloud managed workers) vs. Hybrid (workers on-prem, Leader in Cloud).
  • Verify network connectivity requirements (firewall rules, outbound ports for workers).
  • Confirm authentication/SSO integration (Local, Okta, Azure AD, etc.).
  • Review monitoring/metrics strategy (e.g., forwarding Cribl internal metrics).

3. Configuration Inventory & Export

  • Export routes, pipelines, packs, datasets, and knowledge objects from on-prem Cribl.
  • Validate custom JavaScript functions, regex, and break logic.
  • Export/review environment variables and secrets management.
  • Check version alignment between on-prem and Cribl Cloud (upgrade if needed).

4. Cribl Cloud Setup

  • Provision Cribl Cloud environment (Leader, workspaces, team invites).
  • Configure/Bootstrap worker groups (Cloud workers and/or hybrid on-prem workers).
  • Apply RBAC and team roles.
  • Set up secrets and environment variables in Cloud.

5. Migration Execution

  • Recreate sources, destinations, and routes in Cribl Cloud.
  • Import or manually rebuild pipelines/packs.
  • Validate dataset design (Lake, S3, Blob, etc.).
  • Test routing logic with sample data.
  • Stage migrations by source or dataset (phased approach).

6. Validation & Testing

  • Validate event counts, throughput, and latency before/after migration.
  • Compare output between on-prem and Cribl Cloud for accuracy.
  • Confirm dashboards, alerts, and SIEM/SOAR detections still function.
  • Run canary deployments (limited data sources – start small) before cutover.

7. Cutover & Decommission

  • Plan cutover window and rollback procedures.
  • Redirect production data sources to Cribl Cloud endpoints.
  • Monitor ingestion, routing, and destination health.
  • Archive old configs for rollback/reference.

8. Post-Migration Optimization

  • Review and update documentation (architecture diagrams, runbooks).
  • Conduct knowledge transfer with stakeholders.
