Comprehensive Google SecOps migration checklist for CISOs and SOC leaders

This blog provides a practical, phased checklist for CISOs and SOC leaders migrating from legacy SIEMs to Google SecOps, emphasizing early decisions on detection strategy, scalable multi-cloud data onboarding, and an operating model that avoids alert debt. It details pre-migration inventory and justification, migration execution across data ingestion, detection/content parity, integrations, compliance/retention, and risk/rollback planning, and post-migration optimization via measurable outcomes (MTTD/MTTR, cost, coverage), continuous tuning, AI-assisted triage (e.g., Gemini), decommissioning legacy tools, and governance/reporting to realize scale and cost benefits while managing migration complexity.
