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.
