When undertaking a cloud migration project, some potential high-level epics (also known as features or user stories) that could be created might include:

Assessing current environment: This epic could involve conducting an assessment of the current IT environment to identify any challenges or constraints that need to be addressed during the migration process. This might include identifying dependencies between systems, assessing the complexity of the current environment, and identifying any technical or business risks that need to be mitigated.
Migrating applications and data: This epic could involve the actual process of migrating applications and data from the current environment to the cloud. This might include tasks such as re-architecting applications to be cloud-native, migrating data to the cloud, and testing the migrated applications and data to ensure that they are functioning correctly.
Establishing a cloud governance model: This epic could involve defining and implementing a cloud governance model that outlines how the cloud environment will be managed and governed. This might include defining roles and responsibilities, establishing policies and procedures, and setting up monitoring and reporting mechanisms to ensure that the cloud environment is being used effectively and efficiently.
Implementing security controls: This epic could involve implementing security controls to ensure that the cloud environment is secure and compliant. This might include tasks such as setting up network security controls, implementing identity and access management controls, and establishing incident response procedures.
Ensuring business continuity: This epic could involve implementing measures to ensure that the migrated applications and data are available and accessible to users during and after the migration process. This might include tasks such as setting up failover and disaster recovery processes, testing the resiliency of the cloud environment, and establishing a maintenance and support model to ensure ongoing availability.
These are just a few examples of the types of epics that could be created for a cloud migration project. The specific epics and tasks that are included will depend on the specific goals and requirements of the project.
