Memory Migration Script: Default to Named Project Graphs

Location

/mnt/NV2/Development/cognitive-memory/scripts/migrate-memories.py

Problem

Memories accumulated in the default cognitive-memory graph without project-level separation. Needed a way to migrate them into named project graphs based on tag matching.

Solution

Standalone Python script (migrate-memories.py) that migrates memories from the default cognitive-memory graph to named project graphs.

Key Features

  • Tag-based classification: routes memories to target graphs by matching tags
  • Flags: --dry-run, --no-git, --cleanup-overlaps
  • File operations: moves/copies .md files, updates _index.json, _embeddings.json, _state.json in both source and target
  • Edge handling: classifies edges as migrate vs orphan, strips cross-graph edge references from frontmatter
  • Overlap detection: memories tagged for multiple projects are COPIED (not moved) to each target graph; tracked in _migration_overlaps.json
  • Idempotent: safe to re-run
  • Atomic JSON writes: via tempfile + os.replace()
  • Git auto-commit: commits changes after successful migration
