Migration process phases

There are four phases in the data migration process: analysis, preparation, execution, and post-processing.

Analysis

Before you begin the data migration, do this analysis:
  • Assess the value of the overall migration effort.
  • Run the Migration Metrics utility to assess the data that you want to migrate:
    • Examine the shape and size of the data; for example, the number of objects, links, OLE objects, and attributes.
    • Consider the hygiene of the data in terms of the consolidated type system. Determine the number of attributes of each type and how similar are they to each other.
  • Identify potential risk areas that might impact migration.

Preparation

Based on the results of your analysis, do these tasks to prepare for migration:
  • Harmonize type systems to avoid the proliferation of artifact types in IBM Rational DOORS Next Generation.
    • Check for differences in case sensitivity.
    • Check for inconsistent enumeration values in attributes that share a common name.
  • Remove attributes that have no business value in future work.

Execution

After you complete your analysis and preparation, do these migration tasks:

Post-processing

After the migration packages are imported, do these tasks in Rational DOORS Next Generation:
  • Perform more harmonization of artifact types.
  • Perform typical administrative tasks to set up team areas, users, and access controls.
