Enterprise Platform Migration Guide

📄 Version 4.2.1 📅 Last Updated: November 12, 2026 âąī¸ Est. Read Time: 14 min đŸ›Ąī¸ Classification: Internal / Partner Restricted

Overview & Scope

This guide outlines the standardized procedure for migrating workloads, data pipelines, and integration endpoints to the Aevum Zenth Core Platform (AZCP) v4.2+. The migration framework is designed for cross-divisional consistency while accommodating industry-specific compliance and data sovereignty requirements.

â„šī¸

Scope: Applies to all legacy system decommissions, SaaS integrations, on-premise server migrations, and cross-divisional data syncs. Does not cover emergency hotfix deployments.

Migration windows are scheduled monthly. Rush migrations require Executive Steering Committee approval and must be submitted via the zenth-migration-request CLI or Portal API.

Prerequisites

Before initiating migration, ensure the following conditions are met:

  • Access Credentials: AZCP Admin role, Divisional SSO token, and API keypair (RSA-4096 or Ed25519)
  • Network Configuration: VPN tunnel established to Zenth Core Gateway (port 8443/TLS1.3)
  • Backup Verification: Full state snapshot validated via zenth-snapshot --verify
  • Compliance Sign-off: Divisional Data Officer approval (required for Healthcare, Finance, Defense)
  • Capacity Allocation: Target environment reserved (minimum 15% overhead recommended)
âš ī¸

Warning: Migrating without verified backups may trigger automated rollback protocols and result in temporary service suspension.

Migration Phases

The migration lifecycle follows a six-stage verification pipeline. Each stage requires manual sign-off or automated gate passing before progression.

1

Assessment & Planning

Run the legacy compatibility scanner. Generate a dependency map and identify breaking changes. Submit the Migration Plan Document (MPD) to your division lead.

Terminal
zenth-scan --source legacy-prod-us-east-1 --output mpd-v42.json --deep-deps
2

Environment Setup

Provision the target AZCP workspace. Configure IAM roles, network policies, and storage tiers. Validate connectivity using the health probe.

CLI
zenth-deploy --workspace azcp-division-healthcare-eu \
--tier high-availability \
--validate-connectivity
3

Data Export & Validation

Extract structured/unstructured data from legacy systems. Run checksum verification and schema mapping. Ensure GDPR/HIPAA/SOX compliance flags are applied.

✅

Use --preserve-encryption for sensitive datasets. Cross-divisional data transfers automatically route through Zenth Secure Transit.

4

Execution & Cutover

Initiate the migration stream. Monitor throughput and latency metrics. Upon completion, run integration tests and perform DNS/load balancer cutover.

Migration Stream
zenth-migrate --stream-id mrg-8f4a2c \
--parallel-workers 8 \
--cutover-auto \
--notify ops-channel@zenth.internal

Division-Specific Requirements

While the core migration pipeline is standardized, certain divisions require additional compliance steps or architectural constraints.

Division Compliance Framework Special Requirement Lead Contact

Rollback Procedure

If validation gates fail or critical data corruption is detected, initiate immediate rollback. The system preserves a 72-hour immutable snapshot by default.

🛑

Critical: Rollback must be executed within 15 minutes of failure detection to avoid transactional state divergence.

  1. Stop all active migration streams: zenth-migrate --abort --stream-id [ID]
  2. Trigger rollback protocol: zenth-rollback --source-snapshot latest --force
  3. Verify legacy environment integrity: zenth-health --mode legacy
  4. Restore DNS/routing to pre-migration state
  5. Submit incident report via Portal → Operations → Migration Incidents

Post-rollback, a root cause analysis (RCA) must be completed within 48 hours. Automated rollback attempts are logged in /var/log/zenth/migration-rollback.log.

Support & SLA

Migration operations are supported by the Zenth Core Engineering Team with tiered SLA guarantees:

Tier Response Time Resolution Target Access Method
Standard 4 business hours 48 hours Portal Ticket / Email
Priority 1 business hour 12 hours Dedicated Slack Channel
Critical (P1) 15 minutes 4 hours (24/7) Emergency Warline / PagerDuty
