Figure 5.4 provides an overview of the main page of the Cloud Data
Migration Tool publicly available for free use (http://www.cloud-data-
migration.com). As the user has to provide confidential data following the
guidelines and recommendations of the tool (e.g., access credentials to the
source and target data stores or services for data export and import in the last
step), the user has to register with user, password, and e-mail address. After
a migration project is finalized, the user can print a report of the decisions
made during the migration, the identified conflicts, and their resolutions for
the purpose of documentation and support. Currently, we are supporting
the migration from one source data store to one target data store or service,
and one migration project has to be created per migration. Extending the tool
in order to support more than one target data stores per migration project is
ongoing work.
The Cloud Data Migration Tool is realized as a Java 6 web application and
follows a three-layer architecture. The presentation layer is realized using
