Migrating to DataSafe: Step-by-Step Implementation Plan

Migrating to DataSafe: Step-by-Step Implementation Plan

1. Project kickoff

• Stakeholders: Identify sponsor, IT lead, security lead, application owners, and end-user reps.
• Goals: Define success criteria (e.g., 99.9% data availability, zero data loss, cutover date).
• Timeline & budget: Set target migration window and budget estimate.

2. Inventory & assessment

• Data inventory: Catalog data sources (databases, file shares, cloud buckets, endpoints) with size, owner, and sensitivity.
• Dependency mapping: List applications, integrations, and data flows tied to each dataset.
• Risk assessment: Classify data by sensitivity (e.g., public, internal, confidential, regulated) and identify compliance requirements.

3. Design migration architecture

• Target layout: Define how DataSafe will be organized (tenants/projects, storage tiers, retention policies).
• Network & security: Plan network paths, VPNs or peering, firewall rules, and encryption (in transit and at rest).
• Access model: Map roles, least-privilege permissions, and MFA requirements.
• Backup & rollback: Define fallback procedures and data validation checks.

4. Prepare environment

• Provisioning: Create DataSafe accounts, projects, and storage allocations.
• Connectivity: Establish secure network links and test throughput.
• Access controls: Configure IAM roles, groups, and policies.
• Monitoring & logging: Enable audit logs, alerts, and metrics collection.

5. Pilot migration

• Select pilot datasets: Choose representative low-risk datasets and one critical dataset if feasible.
• Run trial migration: Execute full copy, apply target policies, and validate integrity and performance.
• Validate: Check checksums, application behavior, access control, and restore tests.
• Refine: Tweak scripts, bandwidth throttling, and schedules based on pilot results.

6. Full migration planning

• Migration waves: Break remaining data into waves by risk, size, and dependencies.
• Cutover strategy: Decide between big-bang, phased cutover, or coexistence/sync approach.
• Schedule windows: Set migration windows minimizing business impact; include pre-cutover freeze if needed.
• Communication: Notify stakeholders, support teams, and end users with timelines and rollback contacts.

7. Execute migration

• Data transfer: Use recommended tools (bulk transfer, rsync-style sync, or DataSafe native import) with encryption and integrity checks.
• Apply policies: Configure retention, lifecycle, and classification after data lands.
• Testing per wave: Validate access, app functionality, and perform restore drills for each wave.
• Issue handling: Track incidents, revert if necessary, and document resolutions.

8. Post-migration tasks

• Final sync & cutover: Perform delta sync, switch application endpoints, and retire old storage as appropriate.
• Verification: Run full audits, reconcile counts/sizes, and confirm backups and retention.
• Optimization: Tune policies, lifecycle rules, and cost controls (tiering, cold storage).
• Decommission: Securely delete or archive legacy data stores and revoke unused credentials.

9. Documentation & training

• Runbooks: Create operational runbooks for restores, snapshot management, and incident response.
• Knowledge transfer: Train ops, helpdesk, and application owners on DataSafe workflows.
• SLA & support: Define support tiers, escalation paths, and SLA measurements.

10. Review & continuous improvement

• Post-mortem: Conduct a migration retrospective capturing lessons learned and metrics vs. goals.
• Monitoring: Maintain ongoing audits, compliance checks, and periodic restore tests.
• Roadmap: Plan incremental improvements (automation, cost savings, stronger policies).
