Distills the myriad technical tasks required to give the carved-out entity a secure, autonomous technology stack on Day 1. The checklist clusters activities into infrastructure, applications, data, security, and vendor contracts, specifying what must be inventoried, cloned, migrated, or decommissioned—and by when. It covers actions such as carving out ERP and CRM instances, provisioning new cloud tenants, segmenting networks, migrating identity platforms, validating data-migration mock runs, novating software licences, and setting up interim TSA tunnels. Each line item includes an owner, evidence requirement, and “go/no-go” metric, enabling the PMO to track progress in real time and ensuring no critical system or integration is forgotten during cut-over.
- ERP (Finance, Supply Chain, Manufacturing) – Secure licence novation, complete master-data migration, validate interfaces, run cut-over rehearsal, obtain CFO sign-off.
- Customer Relationship Management (CRM) – Export and cleanse customer data, rebuild integrations with quoting and support tools, execute user-acceptance test, confirm pipeline visibility.
- Human Capital Management / Payroll (HRIS) – Transfer employee data, configure payroll calendars and statutory reports, parallel-run first pay cycle, confirm tax-ID updates.
- Data Warehouse / Business Intelligence – Replicate ETL jobs, migrate historical datasets, rebuild dashboards with new entity codes, test refresh schedules.
- Manufacturing Execution or Service Delivery Platforms – Duplicate production rules or service scripts, validate IoT or shop-floor device connectivity, perform volume stress test.
- Email and Collaboration (Exchange, M365, Google Workspace) – Create new domain, migrate mailboxes, update MX records, enable multi-factor authentication.
- Identity and Access Management (Active Directory, Azure AD, Okta) – Establish new domain forest, migrate user objects and groups, decommission cross-trusts, enforce conditional-access policies.
- Network Infrastructure (WAN, SD-WAN, Firewalls, VPN) – Allocate new IP ranges, deploy edge devices, configure encrypted inter-company tunnels, perform latency and fail-over tests.
- Cloud Environments (AWS, Azure, GCP) – Set up new accounts or subscriptions, replicate VPC/VNet configurations, migrate workloads with encrypted snapshots, cut DNS to new endpoints.
- Security Tooling (SIEM, EDR, DLP) – Install agents on new endpoints, update log collectors, integrate with new SOC, run penetration test and remediate findings.
- Backup and Disaster Recovery – Establish independent backup vaults, execute full-restore test, update run-books, secure off-site replication targets.
- Service Desk and ITSM Platform – Create new instance or segregated tenancy, migrate ticket history, configure knowledge base, publish new support contacts.
- Software-Asset Management (SAM) – Generate baseline licence-usage report, reconcile with vendor entitlements, document compliance evidence for audit.
- Transition-Service Connectivity – Finalise TSA network ACLs, implement bandwidth monitoring, schedule phased shutdown dates, confirm parent SOC monitoring exclusions.
- Day-1 Command Centre – Establish war-room roster, prepare escalation matrix, set success-criteria dashboard, assign on-call engineers for critical systems.
