A practical checklist
- Add the departure date and useful context in equipment notes.
- Archive the inactive equipment after confirming current work is finished.
- Create a new record for its replacement with its own identifiers.
Tractor T1 notes say “Sold September 2026.” It is archived with prior maintenance intact. The replacement gets name T3 and a new serial number; T1’s previous oil changes are not moved to T3.
What to avoid
Archiving does not delete the maintenance history. Do not treat it as an account erasure or a substitute for managing original sale documents.
