Make sure you understand Azure’s shared responsibility model and evaluate the platform’s security features. If necessary, implement additional security measures to protect sensitive data and ensure privacy.
  5. Skills:
    Migrating to Azure requires specific skills and expertise. Assess the capabilities of your team to determine whether the required internal resources are available or whether it may be more effective to partner with a cloud migration service provider. Investing in employee training and support is crucial to ensure a smooth migration and ongoing management of the Azure environment.

Azure migration: Strategy, evaluation and preparation

It is crucial for companies to set their migration goals and identify the applications, data and infrastructure they want to move to Azure. Begin by outlining the goals of the migration, such as cost reduction, improved performance or increased flexibility. Identify the applications, data and infrastructure to be moved to Azure, considering their relevance to your business goals.

  1. Define business objectives:
    It is crucial for companies to set their migration goals and identify the applications, data and infrastructure they want to move to Azure. Begin by outlining the goals of the migration, such as cost reduction, improved performance or increased flexibility. Identify the applications, data and infrastructure to be moved to Azure, considering their relevance to your business goals.
  2. Evaluation:
    Companies should evaluate their current environment, including applications, data and infrastructure, to identify potential issues or challenges that may arise during migration. Assess compatibility with Azure services and identify necessary adjustments to ensure a seamless transition.
  3. Planning and prioritization:
    Based on the results of the evaluation, prepare a detailed migration plan, with timelines, resources and tasks. Prioritize applications, data and infrastructure based on factors such as complexity, risk and business impact to determine the optimal order of migration.
  4. Test migration:
    Before you actually start the migration, perform a test migration in a controlled environment to discover any potential problems or challenges. With this trial run, you can proactively address issues and optimize the migration process to ensure minimal disruption.
  5. Migration:
    Upon completion of testing, you begin the actual migration process, starting with the highest priority applications, data and infrastructure. Follow the migration closely to resolve any issues quickly and keep stakeholders informed of progress.
