Migrate Skill

Universal migration from any wiki, note tool, or brain system into Inbrain.

Contract

• Source data is never modified or deleted; migration is additive only.
• Every migrated page is verified round-trip: written to inbrain, read back, spot-checked.
• Cross-references from the source system (wikilinks, block refs, tags) are converted to inbrain equivalents.
• Migration is tested on a sample (5-10 files) before bulk execution.
• Post-migration health check confirms page count, link integrity, and embedding coverage.

Supported Sources

Source	Format	Strategy
Obsidian	Markdown + [[wikilinks]]	Direct import, convert wikilinks to inbrain links
Notion	Exported markdown or CSV	Parse Notion's export structure
Logseq	Markdown with ((block refs))	Convert block refs to page links
Plain markdown	Any .md directory	Import directory into inbrain directly
CSV	Tabular data	Map columns to frontmatter fields
JSON	Structured data	Map keys to page fields
Roam	JSON export	Convert block structure to pages

Phases

1. Assess the source. What format? How many files? What structure?
2. Plan the mapping. How do source fields map to inbrain fields (type, title, tags, compiled_truth, timeline)?
3. Test with a sample. Import 5-10 files, verify by reading them back from inbrain and exporting.
4. Bulk import. Import the full directory into inbrain.
5. Verify. Check inbrain health and statistics, spot-check pages.
6. Build links. Extract cross-references from content and create typed links in inbrain.

Obsidian Migration

1. Import the vault directory into inbrain (Obsidian vaults are markdown directories)

2. Wire the graph with native wikilink support (v0.12.1+):

   inbrain extract links --source db --dry-run | head -20    # preview
   inbrain extract links --source db                         # commit
   

   extract links natively parses [[relative/path]] and [[relative/path|Display Text]] alongside standard [text](page.md) markdown syntax. Ancestor-search resolution handles wiki KBs where authors omit one or more leading ../ prefixes. The .md suffix is inferred automatically for wikilinks.

Obsidian-specific:

• Tags (#tag) become inbrain tags
• Frontmatter properties map to inbrain frontmatter
• Attachments (images, PDFs) are noted but handled separately via file storage

Notion Migration

1. Export from Notion: Settings > Export > Markdown & CSV
2. Notion exports nested directories with UUIDs in filenames
3. Strip UUIDs from filenames for clean slugs
4. Map Notion's database properties to frontmatter
5. Import the cleaned directory into inbrain

CSV Migration

For tabular data (e.g., CRM exports, contact lists):

1. For each row in the CSV, create a page with column values as frontmatter
2. Use a designated column as the slug (e.g., name)
3. Use another column as compiled_truth (e.g., notes)
4. Store each page in inbrain

Verification

After any migration:

1. Check inbrain statistics to verify page count matches source
2. Check inbrain health for orphans and missing embeddings
3. Export pages from inbrain for round-trip verification
4. Spot-check 5-10 pages by reading them from inbrain
5. Test search: search inbrain for "someone you know is in the data"

Anti-Patterns

• Bulk import without sample test. Never import the full dataset before verifying with 5-10 files. The cost of cleaning up hundreds of bad pages is enormous.
• Destroying source data. Migration is additive. Never modify, move, or delete the source files.
• Ignoring cross-references. Wikilinks, block refs, and tags from the source system must be converted to inbrain equivalents. Dropping them loses the knowledge graph.
• Skipping verification. A migration without post-import health check, page count comparison, and spot-check reads is incomplete.

Output Format

MIGRATION REPORT -- [source] -> Inbrain
=======================================

Source: [format] ([file count] files, [size])
Mapping: [field mapping summary]

Sample Test (N files):
- Imported: N/N
- Round-trip verified: N/N
- Cross-refs converted: N

Bulk Import:
- Total imported: N
- Skipped (duplicates/errors): N

- Tags migrated: N

Verification:
- Page count match: [yes/no]
- Health check: [pass/fail]
- Search test: [query] -> [result count] hits
