The Real Cost of Migrating 10,000 Notes from Evernote

Understanding the Scale

When people talk about migrating from Evernote, casual users with a few hundred notes can usually export and move on without much trouble. The real challenges emerge when you've been using the service for a decade or more and have accumulated thousands of notes.

These aren't edge cases. They're typical of power users who've relied on Evernote as their primary knowledge management system for years. At this scale, "export all notes" isn't a button click—it's a project that requires planning, testing, and often multiple attempts.

The cost isn't monetary. It's measured in hours spent, data lost during transfer, and the mental effort required to rebuild your workflow in a new environment.

The Time Investment

Anyone who's completed a large-scale migration will tell you the same thing: it took longer than expected. Much longer.

Phase 1: Research and Selection

Before you export a single note, you need to decide where you're going. This involves:

• Researching alternatives (Obsidian, Notion, Joplin, OneNote, etc.)
• Understanding each tool's import capabilities
• Testing with small batches of notes
• Evaluating which tool fits your workflow
• Reading migration experiences from other users

For most users, this phase takes 2-4 weeks of casual research. You're not just choosing an app—you're choosing a new philosophy for how your notes will be organized.

Phase 2: Export

Evernote's export functionality has limitations:

• You may need to export notebook by notebook
• Large exports can timeout or fail silently
• ENEX files can be very large at scale
• Attachments significantly increase export time

One user with 18,750 notes documented their migration in a Medium post, noting that the export itself was a multi-step process that required organizing notes into manageable batches.

Phase 3: Import and Cleanup

This is where the real time investment happens. Importing 10,000 notes is rarely seamless:

• Formatting issues require manual fixes
• Broken note links need to be identified and repaired
• Tags may not transfer correctly
• Attachments might not import as expected
• Folder structures need to be recreated

Users report spending anywhere from several weekends to several months on this phase. One user with 1,100 Evernote tags had to write a Ruby script to replace special characters that Obsidian wouldn't accept. Another discovered that their PDF-heavy notes required special handling.

Technical Challenges You'll Encounter

Large-scale migrations surface technical issues that don't appear with smaller exports. Here are the most common challenges reported by users who've migrated thousands of notes.

The Tag Migration Problem

One user's experience is illustrative: they had approximately 1,100 Evernote tags that they'd carefully curated over years. When they tried to migrate to Obsidian, they discovered that special characters (& @ ( ) / .) in their tags weren't accepted.

This wasn't a minor annoyance. Their entire organizational system relied on these tags. They had to write a Ruby script to batch-replace problematic characters with dashes. For users without programming experience, this kind of issue can be a showstopper.

PDF and Attachment Handling

For users who scan documents or store PDFs in Evernote, attachments add significant complexity. One user reported having over 6,000 notes, 90% of which included PDFs from a ScanSnap scanner.

Challenges include:

• PDFs may not embed correctly in Markdown exports
• File size limits can truncate attachments
• Linked images may break during export
• OCR data might not transfer to the new system

Broken Note Links

Evernote allows you to link notes to other notes. This creates a web of connections that users rely on for navigation. Unfortunately, these internal links often break during export.

One user specifically cited "broken note links" as a reason they built their own Evernote-to-Obsidian converter after being frustrated with existing tools. The standard export methods simply didn't preserve the connection structure they'd built.

Data Loss and Formatting Issues

The most frustrating aspect of migration is discovering that some of your data didn't make it through intact. This isn't usually catastrophic—most notes transfer—but the cumulative effect of small losses matters when you're dealing with thousands of notes.

Common Types of Data Loss

Users report varying success rates depending on the export tool used. The Obsidian Importer plugin and YARLE (Yet Another Really Long ENEX Exporter) are commonly mentioned, but both have users who experienced formatting and content loss. This is why some users end up building their own conversion tools.

Rebuilding Your Organization System

Migration isn't just about moving data—it's about adapting to a new way of organizing that data. This is a hidden cost that many users underestimate.

Notebooks vs. Folders vs. Tags

Evernote uses a hierarchy: stacks contain notebooks, notebooks contain notes, and notes can have multiple tags. Other tools organize differently:

• Obsidian uses folders and tags, with no native notebook concept
• Notion uses databases and pages with different relationship models
• Joplin uses notebooks similar to Evernote but with different tag handling

One user with 150+ Evernote notebooks had to reorganize their notes into 52 folders for Obsidian. This wasn't a mechanical transfer—it required reconsidering their entire organizational philosophy.

The Learning Curve

Beyond organization, you're learning a new interface, new keyboard shortcuts, and new features. For users who'd developed muscle memory in Evernote over years, this productivity tax persists for weeks or months after the technical migration is complete.

One user explicitly titled their post "I'm TRYING to love Obsidian... but the transition from Evernote has been tricky." They weren't struggling with the export—they were struggling with the day-to-day reality of using a completely different tool.

The Psychological Cost

There's an emotional dimension to migrating thousands of notes that's rarely discussed. These aren't just data points—they're your thoughts, research, plans, and memories accumulated over years.

Migration Anxiety

Users report anxiety about:

• Losing data during the export/import process
• Not being able to find notes in the new system
• Making the wrong choice of destination app
• Regretting the migration and having to reverse it

Sunk Cost Fallacy

Some users cycle through multiple alternatives, trying Notion, then Obsidian, then something else, before returning to Evernote. One user documented a round-trip journey: Evernote → Notion → Obsidian → Notion → Evernote. They ultimately realized the original platform met their needs.

This represents a significant psychological cost: the time spent, the frustration, and the recognition that sometimes the grass isn't actually greener elsewhere.

How to Prepare Before You Migrate

Given the costs involved, how can you prepare? Here are recommendations based on users who've completed large-scale migrations.

1. Backup First, Always

Before you do anything, create a complete backup of your Evernote data. Export to ENEX format at minimum. Consider multiple export formats if storage allows. This ensures you can always return to your starting point.

2. Test with a Small Batch

Don't migrate everything at once. Export a representative sample of notes—different types, different formatting, different attachment types—and test the import process. This will reveal issues before you're committed.

3. Audit Your Organization

Understand what you have before you migrate. How many notebooks? How many tags? Any special characters in tags? How many attachments? This information helps you anticipate challenges.

4. Plan for the Transition Period

Don't expect to be fully productive in your new tool immediately. There will be a period where you're slower, things don't work the way you expect, and you need to look up how to do basic tasks. Plan for this productivity dip.

Summary and Final Thoughts

Migrating 10,000 notes from Evernote is a significant undertaking that involves time, technical challenges, data loss risk, and psychological adjustment. It's not a decision to make lightly.

Key Takeaways

• Large-scale migrations take weeks or months, not hours
• Tag systems, attachments, and note links are common failure points
• Formatting loss is almost guaranteed to some degree
• Organizational systems may need to be rebuilt from scratch
• The learning curve for a new tool persists long after migration
• Some users migrate in circles, trying multiple tools before returning

The Bottom Line

The cost of migration is real and substantial. But for many users, the alternative—staying with a service that no longer meets their needs—is worse. The key is to go into the process with your eyes open, understanding what's involved rather than expecting a seamless transition.

Whether you migrate or stay, having local backups ensures your notes remain accessible regardless of what happens with any particular service. That's insurance worth having, even if you never end up switching.
