迁移环境规划清单:在迁移之前验证环境准备情况Migration environment planning checklist: Validate environmental readiness prior to migration

作为迁移过程的第一步,需要在云中创建正确的环境来接收、托管和支持迁移资产。As an initial step in the migration process, you need to create the right environment in the cloud to receive, host, and support migrating assets. 本文列出了在迁移之前要在当前环境中验证的内容。This article provides a list of things to validate in the current environment prior to migration.

以下清单与云采用框架的 " 就绪" 方法 中的指南一致。The following checklist aligns with the guidance in the Ready methodology of the Cloud Adoption Framework. 请审阅这一节,以获取有关执行以下任何操作的指导。Review that section for guidance regarding execution of any of the following.

工作类型假设Effort type assumption

本文和清单假设使用重新托管或云转换迁移方法进行云迁移。This article and checklist assume a rehost or cloud transition approach to cloud migration.

治理一致性Governance alignment

对于任何迁移就绪环境,第一个也是最重要的决策是治理一致性。The first and most important decision regarding any migration-ready environment is the choice of governance alignment. 是否就治理与迁移基础的一致性达成了共识?Has a consensus been achieved regarding alignment of governance with the migration foundation? 云采用团队至少应了解这种迁移是在具有有限监管的单一环境、完全受管辖环境工厂还是介于两者之间的某个变体上。At a minimum, the cloud adoption team should understand whether this migration is landing in a single environment with limited governance, a fully governed environment factory, or some variant in between. 有关调控协调的其他指导,请参阅 控制方法For additional guidance on governance alignment, see the Govern methodology.

操作管理对齐Operations management alignment

在将资产迁移到云之前,必须了解有关操作管理的任何要求或约束。Before migrating assets into the cloud, it is important to understand any requirements or constraints regarding operations management. 迁移环境至少应包括满足操作基线所需的任何实现。At a minimum, the migration environment should include any implementations required to meet the operations baseline. 有关操作协调的其他指导,请参阅 管理方法For additional guidance on operations alignment, see the Manage methodology.

云就绪实现Cloud readiness implementation

无论你选择是否在初始迁移中与更广泛的云治理策略保持一致,都需要确保将云部署环境配置为支持工作负荷。Whether you choose to align with a broader cloud governance strategy or not for your initial migration, you will need to ensure your cloud deployment environment is configured to support your workloads.

如果你计划从一开始就让迁移与云治理策略保持一致,则需要应用云治理的五个原则,以指示有关策略、工具链和强制机制的决策,它们有助于确保云环境满足总体企业需求。If you're planning to align your migration with a cloud governance strategy from the start, you'll need to apply the Five Disciplines of Cloud Governance to help inform decisions on policies, toolchains, and enforcement mechanisms that will align your cloud environment with overall corporate requirements. 有关如何使用 Azure 服务实现此模型的示例,请参阅云采用框架指南中的可操作治理设计指南Consult the Cloud Adoption Framework actionable governance design guides for examples of how to implement this model using Azure services.

如果初始迁移没有与更广泛的云治理策略紧密保持一致,仍需要管理整理、访问和基础结构计划的常规问题。If your initial migrations are not closely aligned with a broader cloud governance strategy, the general issues of organization, access, and infrastructure planning still need to be managed. 有关这些云就绪性决策的帮助,请参阅 Azure 设置指南Consult the Azure setup guide for help with these cloud readiness decisions.

注意

强烈建议为除初始工作负荷迁移之外的任何迁移制定治理策略。We highly recommend that you develop a governance strategy for anything beyond your initial workload migration.

无论治理一致性级别如何,都需要做出与以下主题相关的决策。Regardless of your level of governance alignment, you will need to make decisions related to the following topics.

资源组织Resource organization

根据治理一致性决策,应在迁移之前建立资源的整理和部署方法。Based on the governance alignment decision, an approach to the organization and deployment of resources should be established prior to migration.

命名法Nomenclature

应在迁移之前建立一致的资源命名方法以及一致的命名架构。A consistent approach for naming resources, along with consistent naming schemas, should be established prior to migration.

资源调控Resource governance

应在迁移之前做出有关资源治理工具的决策。A decision regarding the tools to govern resources should be made prior to migration. 无需完全实现这些工具,但应选择和测试方向。The tools do not need to be fully implemented, but a direction should be selected and tested. 云治理团队应在迁移之前,定义并要求实现最低可行的产品 (MVP) 用于调控管理工具。The cloud governance team should define and require the implementation of a minimum viable product (MVP) for governance tooling prior to migration.

网络Network

基于云的工作负荷要求通过预配虚拟网络,支持最终用户和管理访问权限。Your cloud-based workloads will require the provisioning of virtual networks to support end-user and administrative access. 根据资源整理和资源治理决策,应选择满足 IT 安全要求的网络方法。Based on resource organization and resource governance decisions, you should select a network approach align it to IT security requirements. 此外,网络决策还应遵守任何混合网络约束,这些约束为运营迁移积压工作中的工作负荷并支持访问本地托管资源所需。Further, your networking decisions should be aligned with any hybrid network constraints required to operate the workloads in the migration backlog and support any access to resources hosted on-premises.

标识Identity

基于云的标识服务是为云资源提供标识和访问管理 (IAM) 的先决条件。Cloud-based identity services are a prerequisite for offering identity and access management (IAM) for your cloud resources. 在继续之前,请先协调标识管理策略和云采用计划。Align your identity management strategy with your cloud adoption plans before proceeding. 例如,在迁移现有本地资产时,建议使用目录同步支持混合标识方法,以便在迁移期间和迁移之后能够跨本地和云环境使用一组一致的用户凭据。For example, when migrating existing on-premises assets, consider supporting a hybrid identity approach using directory synchronization to allow a consistent set of user credentials across you on-premises and cloud environments during and after the migration.

后续步骤Next steps

如果环境满足最低要求,可视为环境获准具有迁移就绪性。If the environment meets the minimum requirements, it may be deemed approved for migration readiness. 文化复杂性和变更管理有助于协调角色和责任,以确保在执行计划期间实现适当预期。Cultural complexity and change management helps to align roles and responsibilities to ensure proper expectations during execution of the plan.
