Cloud Migration: What the Process Looks Like and What Its Stages Are

November 29, 2023

The importance of a solid strategy before migration 

As we said at the beginning, the cloud is the future of business. More and more organizations are aware of the benefits of migrating their infrastructures, applications, and data to these platforms. However, migration is not a trivial or automatic process. It requires a solid strategy that considers all the technical, operational, financial, and legal aspects involved in the change. So what should you do? Developing a strategic plan is where you should start, as it allows you, among other things, to: 

  • Define your goals and expectations Before migrating, you must be clear about what you want to achieve with the cloud and how you will measure success. For example, you may want to reduce costs, improve performance, increase security, or facilitate innovation. 
  • Evaluate your current infrastructure and select the best cloud option: Not all data and applications can be migrated in the same way or adapted to the same cloud solution. You need to analyze your existing infrastructure and determine which type of cloud (public, private, or hybrid) and which service model (IaaS (Infrastructure as a Service), PaaS (Platform as a Service), or SaaS (Software as a Service)) best fit your needs and requirements. 
  • Plan the migration step by step: Cloud migration is a process that involves several phases, from preparation to optimization. You must establish a detailed plan that defines what will be migrated, in what order, how it will be done, and who will be responsible. You must also anticipate potential risks and contingencies, and establish control and monitoring mechanisms. 
  • Empowering your team and managing change: Migrating to the cloud represents a cultural and organizational shift that affects all levels of the company. You must ensure that your team is prepared and motivated to work on it, and that they have the necessary tools, know-how, and support. You also need to communicate the benefits and challenges of the migration to all stakeholders, and manage expectations and resistance to change.

On the other hand, these types of strategies must meet certain requirements. Among them are: 

  • Aligning migration with business goals: A cloud migration strategy must align with the organization's vision, mission, and objectives. This ensures that the migration adds value and meets your company's needs and expectations. 
  • Optimize the migration process: Minimize time, cost, and impact on operations. To do this, define the scope, method, order, and pace of the migration, as well as the resources and tools needed to carry it out. 
  • Mitigate risks and challenges: It is necessary to identify and mitigate the risks and challenges that may arise during the migration process. These can be technical, operational, financial, legal, or human in nature. An adequate strategy should include prevention, detection, and correction measures, as well as contingency and recovery plans. 

 It is necessary to have knowledge and experience before starting the research, planning, and execution of the migration process for several key reasons: 

On the other hand, it is not advisable to venture into the cloud without prior knowledge or experience. These attributes are essential to ensure project success because they help to: 

  • Understanding the implications of cloud migration: Knowledge and experience allow for understanding the technical, operational, financial, and legal implications of cloud migration. This enables the evaluation of the convenience, feasibility, and return on investment of the migration, and the making of informed and sound decisions. 
  • Selecting the best cloud option for the organization: There are different types of cloud (public, private, or hybrid) and different service models (IaaS, PaaS, or SaaS) that adapt to different needs and requirements. Prior know-how is essential to avoid making mistakes when choosing the type of infrastructure to migrate to.  
  • Design and Implement an Effective Cloud Migration Strategy Knowledge and experience enable the design and implementation of an effective cloud migration strategy that meets established objectives, requirements, resources, timelines, responsibilities, and risks. They also allow for the resolution of problems and unforeseen issues that may arise during the migration process. 

Cloud Migration Checklist 

tools that greatly assist in complementing your migration strategy are Checklist o checklists, which among other things allow: 

  • Organize tasks and resources: This way, you can assign responsibilities, priorities, and deadlines, and avoid oversights or delays. 
  • Control progress and quality This way you can ensure that objectives, requirements, standards, and best practices are met, and detect and correct potential errors or deviations. 
  • Communicate and report progress These lists are important for communicating and reporting the progress of the migration process to stakeholders. In other words, you can report on the status, achievements, issues, and risks of the migration, and get feedback and support. 

Additionally, checklists serve as an educational guide for the team and stakeholders, as they explain the concepts, benefits, and challenges of cloud migration. On the other hand, they facilitate documentation and evaluation of the migration process, allowing for learning and the development of best practices for future projects. 

 What are the essential phases of a successful migration? 

Up to this point, we've seen the benefits of a good migration strategy and the importance of checklists as a complementary tool. Now, it's time to delve deeper and detail the stages that make up a plan of this nature. 

Discovery Phase This phase consists of analyzing the existing landscape and infrastructure to identify assets, dependencies, requirements, and migration costs. Key Performance Indicators (KPIs) that will measure the success of the process and return on investment must also be formulated. Additionally, critical points of the legacy infrastructure, such as obsolete systems, security vulnerabilities, or performance bottlenecks that could hinder or impede migration, must be identified. It is also important to define the key factors that will contribute to the success of cloud infrastructure, such as increased flexibility, adaptability, productivity, or creativity. Finally, keep in mind that it is essential to involve stakeholders so that they understand the business vision and objectives. 

Design Phase: This involves selecting the cloud deployment model that best suits the organization's needs and objectives. There are four types of clouds: public, private, community, and hybrid. Each has its advantages and disadvantages, which should be carefully evaluated. The right cloud provider must also be chosen, considering factors such as service offerings, technical support, security, compliance, availability, and price. Additionally, the infrastructure architecture must be documented, defining the components, relationships, configurations, and requirements of each element. 

Migration Phase:  It consists of executing the migration of infrastructure, applications, and data from the on-premises environment to the cloud environment. Various strategies can be used for this. For example, Gartner's 5 Rs. Each strategy has its benefits and challenges, which must be considered on a case-by-case basis. Appropriate tools must also be used, and benchmark, performance, and functional tests should be included for each application.

Go-Live Phase: This phase consists of bringing the infrastructure, applications, and migrated data into operation in the cloud, and verifying that everything works correctly. For this, the following considerations must be taken into account: 

  • Perform final tests before implementation to ensure there are no errors, failures, or inconsistencies. 
  • Have a recovery plan in case of problems, so you can return to the local environment if the migration is unsuccessful or if major issues arise. 
  • Communicate the change to users and customers to inform them about the benefits, new features, and potential service disruptions during the migration. 

Continuous Support Phase: It consists of maintaining and monitoring the cloud environment to ensure its optimal functioning, security, and performance. Having the support of cloud experts who can resolve doubts and implement best practices and innovative solutions is an important part of this stage. 

 Why is it necessary to consult with a cloud partner? 

 Cloud migration is a strategic project that can bring great benefits to organizations looking to innovate and grow in the digital world. However, as we have seen, it is not a trivial or automatic process. It requires a solid strategy that considers all the necessary technical, operational, financial, and legal aspects. A successful migration involves respecting certain essential phases, such as those we have described in this text: discovery, design, migration, launch, and ongoing support. Each of these has its own objectives, requirements, resources, deadlines, responsibilities, and risks, which must be properly defined and managed. In this regard, a checklist can be a very useful tool, as it allows for the organization, control, communication, and reporting of migration process progress.  

Furthermore, when considering the leap to the cloud, one thing must be clear: significant knowledge and experience are required to select the best cloud option for your organization. A good choice will allow you to design and implement an optimal infrastructure architecture, execute the move of data and applications efficiently and securely, and verify that everything functions correctly. If that weren't enough, once you've migrated, you'll need to maintain and monitor the environment to ensure optimal operation, security, and performance. None of this is possible without the support of specialized partners.
