Data migration
, "nearly 40 percent of data migration projects were over time, over budget, or failed entirely." As such, to achieve an effective data migration, proper planning is critical. While the specifics of a data migration plan may vary—sometimes significantly—from project to project, the computing company IBM suggests there are three main phases to most any data migration project: planning, migration, and post-migration. Each of those phases has its own steps. During planning, dependencies and requirements are analyzed, migration scenarios get developed and tested, and a project plan that incorporates the prior information is created. During the migration phase, the plan is enacted, and during post-migration, the completeness and thoroughness of the migration is validated, documented, closed out, including any necessary decommissioning of legacy systems. For applications of moderate to high complexity, these data migration phases may be repeated several times before the new system is considered to be fully validated and deployed.

During the migration process, user data is captured from the source OS, and transferred to the Windows 7 environment. This is achieved by running the migration software on both systems and choosing their respective roles when prompted by the application. The application auto-detects migration settings. An "Advanced" option allows the user to customize the migration process, allowing sources and targets to be customized. Custom filters can limit the data transferred, e.g. skipping archives and files larger than 100MB in size.
