The starting point
An initial inventory can use categories, systems and ranges without transferring records. Before a later evaluation, confirm what is retained, how events connect and which gaps or changes affect the proposed scope.
A practical order of work.
- Distinguish company age from the history actually retained in each source system.
- Check links, duplicates, timestamps and changes across migrations or revisions.
- Document exclusions and unknowns before budgeting for a scoped evaluation.
