Before executing on migration, ensure that you have a migration plan and that you have identified the sprint teams and schedules, created a prioritized backlog, and notified all the application stakeholders about the migration schedule, timelines, and their roles and responsibilities. You must also ensure that the target environment in the cloud has already been set up with the foundational architecture and core services. You might have some application-specific pre-steps, such as performing a backup or sync before migration, shutting down the servers, or unmounting disks and devices from the server.

Make sure you have good network connectivity with the cloud environment during the migration process. A good estimate of the amount of data that needs to be migrated also helps you properly estimate the time it will take to migrate your data to the cloud, given other factors such as bandwidth and network connectivity. You also need to understand the tools that are available to perform the migration. Given the number of devices that are available in the market, you might have to narrow down the selection criteria based on your requirements and other constraints.

As you know, rehost is often the fastest way to migrate your application to the cloud. When the application is running in the cloud, you can further optimize it to leverage all the benefits that the cloud has to offer. By quickly migrating your applications to the cloud, you may start realizing the cost and agility benefits sooner.

Depending on the migration strategy, you typically migrate the entire server, including the application and the infrastructure that the application is running on, or just the data that belongs to an application. Let's look at how to migrate data and servers.
