Statement of Work (SOW)

Service Overview

Database Migration Service provides user, role, permission, schema, and data migration and verification, service tests, performance tuning, and rollout and cutover, all customized to customer requirements. The process is broken down into phases: migration evaluation, solution design, technical verification, migration drill, migration implementation, and acceptance. This process makes it easier for the customer to smoothly migrate their source databases to destination databases.

Service Scope

  1. Service Items Covered

    Huawei will evaluate and clarify migration details, solution design, and data migration, including an evaluation of the workloads involved and the data to be migrated.

  2. Non-Covered Service Items
    • Installation and deployment of application software and databases
    • Connectivity components required for migration
    • Business-related migration performed by the customer, and technical support provided by Huawei

Prerequisites

The customer must submit a request at least 5 working days in advance so that Huawei Cloud can evaluate customer requirements and arrange for the technical experts accordingly.

Service Content

Phase

Description

Migration evaluation

Obtain source database details with customer approval. Assess the feasibility, risks, and resource requirements of database migration.

Planning and design

Verify the hardware devices, network conditions, service requirements, migration plans, and migration/rollback solutions of the database migration based on the collected information, and create a solution that will ultimately be used.

Delivery

Migrate the workloads from the source database to the destination database and optimize performance, ensuring minimal impact on existing applications. After the migration is complete, make sure all applications are running properly.

Acceptance

After the database migration is complete, invite the customer to accept the database migration service.

Acceptance Criteria

  1. Acceptance items:

    Project acceptance starts when the following items have been produced:

    • Database Migration Checklist
    • Database Migration Implementation Runbook
    • Database Migration Solution Design
  2. Acceptance process
    • Huawei produces project deliverables and performs a self-check. After the deliverables pass the check, Huawei submits an acceptance application.
    • The customer reviews and signs for all deliverables that meet requirements. If the deliverables do not meet requirements, Huawei modifies them based on comments provided and then resubmits for acceptance.
    • Huawei modifies and resubmits deliverables to the customer for acceptance within five working days when review comments were received.
