Execute major Obsidian plugin rewrites and migration strategies.
Use when migrating to or from Obsidian, performing major plugin rewrites,
or re-platforming existing note systems to Obsidian.
Trigger with phrases like "migrate to obsidian", "obsidian migration",

Migrate notes from Notion, Evernote, Roam Research, Bear, and Apple Notes into Obsidian -- handling attachment relocation, internal link conversion to [[wikilinks]], tag migration, and frontmatter generation.
Prerequisites
Exported data from the source application (see each section for format)
A target Obsidian vault created and opened at least once
Notion exports as a zip containing markdown files, CSV databases, and attachments. The markdown uses Notion-style links and has UUIDs appended to filenames.
Roam exports as JSON with a flat array of pages containing children blocks.
// roam-to-obsidian.mjsimport { readFile, writeFile, mkdir } from'fs/promises';
import { join } from'path';
constROAM_JSON = process.argv[2];
constVAULT_DIR = process.argv[3];
functionconvertBlock(block, depth = 0) {
let md = '';
const indent = ' '.repeat(depth);
const text = convertRoamSyntax(block.string || '');
if (depth === 0) md += text + '\n\n';
else md += `${indent}- ${text}\n`;
for (const child of block.children || []) {
md += convertBlock(child, depth + 1);
}
return md;
}
functionconvertRoamSyntax(text) {
// ((block-refs)) -> just the text (can't resolve without full graph)
text = text.replace(/\(\(([^)]+)\)\)/g, '$1');
// {{[[TODO]]}} -> - [ ]
text = text.replace(/\{\{(\[\[)?TODO(\]\])?\}\}/g, '- [ ]');
// {{[[DONE]]}} -> - [x]
text = text.replace(/\{\{(\[\[)?DONE(\]\])?\}\}/g, '- [x]');
// [[page links]] -> [[page links]] (already wikilink format)// #[[tag]] -> #tag
text = text.replace(/#\[\[([^\]]+)\]\]/g, '#$1');
// ^^highlight^^ -> ==highlight==
text = text.replace(/\^\^(.+?)\^\^/g, '==$1==');
return text;
}
asyncfunctionmigrate() {
const raw = awaitreadFile(ROAM_JSON, 'utf-8');
const pages = JSON.parse(raw);
awaitmkdir(VAULT_DIR, { recursive: true });
let count = 0;
for (const page of pages) {
const title = (page.title || `Untitled-${count}`).replace(/[<>:"/\\|?*]/g, '-');
const editTime = page['edit-time'] ? newDate(page['edit-time']).toISOString().split('T')[0] : '';
let content = '---\n';
content += `title: "${title}"\n`;
content += `source: roam\n`;
if (editTime) content += `modified: ${editTime}\n`;
content += `migrated: ${newDate().toISOString().split('T')[0]}\n`;
content += '---\n\n';
content += `# ${title}\n\n`;
for (const child of page.children || []) {
content += convertBlock(child);
}
awaitwriteFile(join(VAULT_DIR, `${title}.md`), content);
count++;
}
console.log(`Migrated ${count} pages from Roam Research`);
}
migrate().catch(console.error);
Step 5: Bear Notes Migration
Bear exports markdown with Bear-specific tags (#tag/subtag#) and image references that need conversion.
#!/bin/bash# bear-to-obsidian.sh <bear-export-dir> <vault-dir>
BEAR_DIR="$1"
VAULT_DIR="$2"
ATTACH_DIR="$VAULT_DIR/attachments"mkdir -p "$ATTACH_DIR"
count=0
for note in"$BEAR_DIR"/*.md; do
[ -f "$note" ] || continue
filename=$(basename"$note")
# Fix Bear nested tags: #project/active# -> #project/active# Fix Bear tag spacing: #tag1 #tag2 (already compatible)
content=$(sed -E 's/#([a-zA-Z0-9/_-]+)#/#\1/g'"$note")
# Convert Bear image syntax: [image:UUID/filename.png]
content=$(echo"$content" | sed -E 's/\[image:([^]]+\/)?([^]]+)\]/![[\2]]/g')
# Add frontmatter if missingif ! echo"$content" | head -1 | grep -q '^---'; then
title=$(echo"$filename" | sed 's/\.md$//')
content="---
title: \"$title\"
source: bear
migrated: $(date +%Y-%m-%d)
---
$content"fiecho"$content" > "$VAULT_DIR/$filename"
count=$((count + 1))
done# Copy Bear attachments (usually in a parallel directory)if [ -d "$BEAR_DIR/assets" ]; thencp -r "$BEAR_DIR/assets/"* "$ATTACH_DIR/" 2>/dev/null
fiecho"Migrated $count notes from Bear"
Step 6: Apple Notes Migration
Apple Notes has no native export. Use apple-notes-liberator or export via AppleScript (macOS only):
# Export Apple Notes to HTML, then convert to Markdown
osascript -e '
tell application "Notes"
repeat with n in every note
set fp to (POSIX path of (path to desktop)) & name of n & ".html"
set f to open for access fp with write permission
write body of n to f as «class utf8»
close access f
end repeat
end tell
'# Convert exported HTML files to Markdown with frontmatter
npm install turndown
for f in ~/Desktop/*.html; do
node -e "
const td = new (require('turndown'))({headingStyle:'atx'});
const html = require('fs').readFileSync('$f','utf-8');
const title = require('path').basename('$f','.html');
const md = '---\ntitle: \"'+title+'\"\nsource: apple-notes\nmigrated: ${new Date().toISOString().split('T')[0]}\n---\n\n'+td.turndown(html);
require('fs').writeFileSync('$1/'+title+'.md', md);
" ~/my-vault
done
Markdown notes with [[wikilink]] syntax and frontmatter (title, source, migrated, tags)
Attachments relocated to attachments/ with ![[embed]] references
Validation report listing broken links, orphaned attachments, and encoding issues
Error Handling
Issue
Cause
Solution
Encoding errors (\ufffd characters)
Source notes not UTF-8
Detect encoding with file command, convert with iconv -f LATIN1 -t UTF-8
Broken wikilinks after migration
File renamed or in subfolder
Run validation script; fix with search-and-replace
Missing attachments
Source export didn't include them
Re-export from source app with "include attachments" option
Duplicate filenames
Same title in different notebooks/folders
Prefix with source folder name: Notebook - Title.md
ENEX parse failure
Malformed XML (common with large exports)
Split ENEX into smaller chunks; export one notebook at a time
Notion CSV issues
Commas or quotes in cell values
Use csv-parse instead of string splitting
Examples
Notion (500 notes): Unzip export, run notion-to-obsidian.mjs, then validate-migration.sh. Typical issues: CSV databases need manual review, nested page hierarchies may need folder restructuring.
Evernote (2000 notes): Export one notebook at a time as ENEX to avoid XML parsing issues. Tags map directly to Obsidian frontmatter tags. Embedded images are extracted as attachments.
Roam Research: Wikilinks already compatible. Main work is converting (()) block refs and {{TODO}}/{{DONE}} syntax.
