Automating large-scale server migrations with CloudEndure Migration Factory

Many companies today want to migrate their servers to Amazon Web Services (AWS) as quickly as possible. This is not an easy job, especially if you want to migrate thousands of servers in a short period of time, such as 6–12 months.
Large-scale migrations present a few challenges:
-
Integrating multiple tools is difficult. There are many tools that support migration, such as discovery tools, migration tools, and configuration management database (CMDB) tools. These tools must be connected so that data flows from one tool to another. However, different tools use different data formats, and that makes integration difficult. A migration is more likely to be successful if there is a way to integrate all the tools.
-
Manual processes are slow and hard to scale. Migrations involve many small tasks, and each task takes a few minutes to complete. A migration is faster when these tasks are automated.
CloudEndure Migration Factory (CEMF) was designed to solve these problems for migrations
that require rehosting (lift and shift). CloudEndure
This guide describes the CEMF process for rehosting servers at scale, for migration architects, program managers, and technical leads. For more information about migration factories, see Mobilize your organization to accelerate large-scale migrations on the AWS Prescriptive Guidance website.
