Set Up and Migration Services

Set Up and Migration Services typically includes:

• ✓Preparation and configuration of target cloud environments
• ✓Identity and access configuration
• ✓Network connectivity and security setup
• ✓Migration of emails and mailboxes, files and document repositories, calendars and collaboration data, applications and services, user accounts and permissions, document types and related metadata
• ✓Linked components and compound structures migration
• ✓Data validation and integrity checks
• ✓Decommissioning or handover of legacy systems

Before any migration activity begins, existing backup arrangements are reviewed and validated to ensure data can be recovered if required. Where necessary, additional pre-migration backups are taken to provide a secure rollback point. During migration, data is transferred using secure, controlled processes with verification checks to confirm completeness and accuracy. Post-migration, backup and recovery mechanisms are implemented or updated in the target environment to align with business continuity requirements. Disaster recovery considerations are built into the target design, including geographic redundancy, failover strategies, and recovery testing where applicable.

Migration activities are subject to agreed maintenance windows and change management processes to minimise business disruption. Some legacy systems may have technical limitations that restrict migration approaches or require remediation before migration. Highly bespoke applications or unsupported platforms may require additional analysis or custom migration tooling. The service is typically delivered remotely, with on-site support available by agreement.

Service levels for Set Up and Migration Services are defined around delivery milestones rather than operational SLAs. These include: • Migration readiness sign-off • Successful completion of migration waves • Validation and acceptance criteria • Hypercare and stabilisation periods Clear communication is maintained throughout delivery, with progress updates, issue tracking, and escalation procedures.

Following migration, a defined hypercare period provides enhanced support to address any issues that arise as users transition to the new environment. This includes troubleshooting, configuration adjustments, and performance tuning. After hypercare, support can transition into ongoing cloud support services, ensuring continuity and long-term stability.

• Administrative or delegated access to source and target systems
• Network connectivity between environments
• Access to identity and directory services
• Availability of subject matter experts for validation and testing
• All access is granted on a least-privilege basis and reviewed regularly.

Migrations are planned to minimise downtime, using phased approaches, parallel running, or off-hours cutovers where appropriate. Detailed rollback plans are defined to address unexpected issues. Planned outages are communicated in advance, with clear timelines and impact assessments. Emergency issues are handled through established incident management processes.

Set Up and Migration Services support public cloud platforms, private cloud environments, and hybrid cloud architectures. Target hosting locations are selected based on data residency, compliance, performance, and resilience requirements.

Customer data remains fully owned by the customer throughout the migration process. Upon completion or exit, all migrated data is accessible in the target environment, and any residual data held by migration tooling is securely deleted. Documentation and migration artefacts are provided to support future operations.
