MIGRATION OVERVIEW

Why teams migrate from Confluence to Notion

Notion has a native Confluence importer — both a ZIP-file path (up to 5 GB) and an API importer (up to 30 GB / ~50k pages) — but for enterprise documentation with nested macros, complex page hierarchies, thousands of internal links, or attachment-heavy content, the importer's limits hit fast and content degrades silently.
Confluence is a wiki built on XHTML-based storage format with embedded macros, deep parent-child page trees, and granular space-level and page-level permissions. Notion is a block-based document platform where content is composed of typed blocks — text, toggles, callouts, databases — with a flat teamspace permission model. Macros are the fundamental gap: Notion has no macro system, so every Confluence macro degrades to the nearest block type or is dropped entirely.
Every migration must handle the 30 GB API ceiling, broken internal links (Notion does not remap Confluence page IDs), unreferenced attachments silently dropped during import, and the complete loss of Confluence's permission model. For large documentation sets, internal link remediation alone is the most time-consuming post-migration task.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Confluence to Notion migration.

Most Critical

Macro Degradation

Most Confluence macros are unsupported. Nested bodied macros flatten to plain text, LaTeX blocks fail to render, and Gliffy diagrams are dropped unless pre-converted to images before import.

Broken Internal Links

Notion does not remap Confluence internal links during import. Every cross-reference between pages breaks and must be rebuilt via a page-ID-to-Notion-URL mapping pass.

Size & File Count Limits

ZIP importer caps at 5 GB (15 GB on request) and archives with 10,000+ files can fail. The API importer supports up to 30 GB but larger imports may fail with no resume capability.

Permission Model Loss

Confluence's granular space-level and page-level permissions are not replicated. All content lands under a single private root and access must be rebuilt manually in Notion teamspaces.

Unreferenced Attachments

Attachments and media not explicitly embedded in page bodies are silently dropped during import — files used as a repository on Confluence pages vanish without warning.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Confluence to Notion and built proven solutions for each one.

Confluence to Notion Migration: Limits, Macros & Broken Links

Notion's importer caps at 30GB and degrades most macros. Internal links all break. Enterprise migrations need managed pipelines for macro mapping, link preservation, and zero downtime.

What does an Engineer-led migration mean anyway?

Speed & Accuracy: Our Blended Method

We blend automation (smart scripts, bulk APIs) with human expertise for speed without risk. Our engineers manually check every mapping, validation, and exception.

You get:

  1. Speed of automation for bulk record migration
  2. Precision of engineers verifying integrity and business logic
  3. Pilot migrations and sandbox testing to catch issues early
  4. Real-time validation reports and rollback readiness
Result: 50x faster migrations than manual imports — with near-zero error rates.

Handling the Tricky Tech and API Details

The Confluence and Notion APIs each behave differently, which is where our engineers shine. We build custom logic to handle the data quirks where generic tools typically break.

We handcraft API logic for:

  1. Field mapping and transformation
  2. Pagination, rate-limit handling, and throttling
  3. Preserving conversation threads, attachments, and internal notes
  4. Syncing custom fields, SLAs, and macros without breaking structure
Our scripts: Natively retry failed calls, re-queue large attachments, and ensure data parity.

No Guesswork

We don't just promise smooth migrations—we measure and prove them. Every client receives a Migration Validation Report with all metrics.

Typical results across projects:

  1. 100% record-count parity between your Confluence data and Notion
  2. Zero downtime during staged cutovers
  3. 99.9% attachment integrity (verified via checksum)
  4. Full automation and preservation of all business rules
Our standard: Includes full SLA preservation and 48 hours of engineer-assigned support post go-live.

We Adapt to Your Setup (Not the Other Way Around)

No two teams configure Confluence or Notion exactly the same way—with unique automations and data. We customize every migration script to fit your exact workflow, tags, and triggers.

Our engineers adapt for:

  1. Custom fields, ticket forms, and workflows
  2. Multi-brand or multi-language setups
  3. Historical imports and partial (date-based) migrations
  4. Integration re-mapping for CRMs, chat, or feedback tools
The promise: If your data doesn't fit a standard template, we build one just for you.

FAQ

Frequently Asked Questions

Everything you need to know about migrating from Confluence to Notion. Can't find what you're looking for? Talk to our team.

What are the size limits for Notion's Confluence importer?
The ZIP-file importer supports up to 5GB (15GB upon request). The API importer supports up to 30GB and ~50k pages. Notion's ZIP docs also warn that 10,000+ files can fail even under the size limit. Workspaces larger than 30GB must be split or migrated using custom pipelines.
Do Confluence macros work after migrating to Notion?
Most Confluence macros are unsupported. Notion maps them to the nearest block type (e.g., Expand → Toggle), but complex macros like nested bodied macros, ui-steps, Page Properties, and LaTeX blocks degrade to plain text or are dropped entirely.
How do I fix broken internal links after migrating Confluence to Notion?
Notion does not remap Confluence internal links during import. You need to build a mapping of old Confluence page IDs to new Notion page URLs and run a find-and-replace across all imported pages. ClonePartner does this automatically during migration.
Can I migrate Confluence comments and users to Notion?
Only the API importer retains comments and maps Confluence users to Notion users by email or username. The ZIP-file importer does not carry over comments or user attribution. Atlassian's HTML export also excludes page comments.
How do I migrate Confluence Databases to Notion?
Treat Confluence Databases as a separate migration stream. Standard page exports do not retain database content or functionality. Export each database to CSV, import into Notion, then rebuild relations, rollups, and formulas manually.
How long does the Confluence to Notion migration take?
Most migrations complete within 1–5 business days, depending on data volume and complexity. We provide a detailed timeline after the initial assessment and can often complete small migrations in under 24 hours.
Will my team lose access to Confluence during the migration?
No. Your source system remains fully operational throughout the entire migration. We run the migration in the background with zero downtime to your current operations.
Will there be downtime when migrating from Confluence to Notion?
No. Our migration process is designed for zero downtime. We use a staged approach with background sync and a fast cutover, ensuring no disruption to your live business operations.
How do I validate that everything migrated correctly?
Every client receives a Migration Validation Report with comprehensive metrics including record-count parity, attachment integrity verification via checksum, and full audit logs. We also offer unlimited sample migrations so you can verify before committing.
Do I need professional help for this migration?
While simple migrations can sometimes be handled in-house, professional help ensures zero data loss, proper field mapping, and preservation of relationships between records. Our engineer-led approach catches edge cases that automated tools miss.
Does ClonePartner provide guidance before committing?
Yes. We provide a free consultation and assessment. We'll review your data structure, discuss your requirements, and provide a detailed migration plan and fixed-price quote before you commit to anything.
