Upgrading from SuperLocalMemory V2 to V3 is a one-command process. No data is lost.

• Three operating modes (A/B/C) — choose your privacy/accuracy trade-off
• 4-channel retrieval — semantic, keyword (BM25), entity graph, and temporal search working together
• Mathematical foundations — information-geometric similarity, consistency checking, self-organizing lifecycle
• Scene and bridge discovery — connects related memories across conversations
• Cross-encoder reranking (Mode C) — precision ordering of results
• Enhanced entity resolution — smarter deduplication and linking

1. Back up your database (recommended but not required — migration creates an automatic backup):

cp ~/.claude-memory/memory.db ~/.claude-memory/memory.db.backup

2. Update to the latest version:

npm install -g superlocalmemory@latest

3. Check migration readiness:

slm migrate --status

Run the migration command:

slm migrate

The migration will:

1. Create a backup of your V2 database
2. Add V3 tables (entity graph, scenes, temporal events, math state)
3. Add V3 columns to existing tables
4. Re-index memories for 4-channel retrieval
5. Build the entity graph from existing memories
6. Move the database to ~/.superlocalmemory/ (with symlink from ~/.claude-memory/)
7. Update IDE configurations

This takes 1-5 minutes depending on database size.

Everything from V2 carries over:

• All stored memories (content, tags, timestamps, importance)
• All profiles and profile isolation
• Trust scores per agent
• Learning system state (LightGBM models, patterns)
• Provenance chains
• Compliance settings (retention policies, audit logs)
• Knowledge graph data

Verify the migration succeeded:

slm status
slm health

Check your memory count matches what you had before.

If anything goes wrong, rollback within 30 days:

slm migrate --rollback

This restores your V2 database from the automatic backup and reverts IDE configurations.

Will my IDE connections break? No. The migration updates IDE configs automatically. The ~/.claude-memory/ path is symlinked to ~/.superlocalmemory/, so old paths still work.

Do I need to re-store my memories? No. All existing memories are preserved and re-indexed for V3's 4-channel retrieval.

Can I go back to V2? Yes, use slm migrate --rollback within 30 days. After 30 days, the backup is automatically removed.

Does migration require an internet connection? No. The migration is entirely local.

How long does it take? 1-5 minutes for typical databases (under 50,000 memories). Larger databases may take longer.
