MIGRATION OVERVIEW

Why teams migrate from Slab to Confluence

There is no native migration path from Slab to Confluence — no connector, no plugin, no one-click wizard. Confluence's import options do not list Slab as a source.
Slab exports content as Markdown files. Confluence requires content in Atlassian Document Format (ADF), a JSON-based document tree — or its legacy XHTML-based Storage Format, which Atlassian is fully deprecating in April 2026.
Every migration requires ADF translation, topic-to-space mapping, multi-pass internal link rewriting, and image re-hosting — all API-driven to bypass the 200 MB XML import limit.
KEY CHALLENGES

What makes this migration complex

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

Most Critical

ADF Translation

Slab Markdown must be converted to Atlassian Document Format JSON with custom rules for callouts, embeds, and code blocks.

Topic-to-Space Mapping

Slab posts can belong to multiple topics. Confluence pages live in exactly one space with a strict parent-child tree.

Internal Link Rewriting

Every Slab URL must be replaced with Confluence page links via a three-pass migration strategy.

Image Re-hosting

Inline images reference Slab's CDN and must be downloaded and re-uploaded as Confluence attachments with updated ADF media nodes.

Secret Topic Access

Slab's API only returns content the Bot user can access. Secret topics are silently excluded without an access audit.

MIGRATION RISK ASSESSMENT

What breaks during migration

Not everything moves cleanly between platforms. Our engineers have mapped every data type from Slab to Confluence and assessed the migration risk for each.

Data Type Status
Data Loss Risk
Internal Links
All Slab URLs break post-migration — require three-pass rewriting
Breaks
Comments & Discussions
Absent from export and API — cannot map to Confluence inline comments
Breaks
Embedded Integrations
GitHub, Figma, and Loom embeds degrade to bare URLs with no ADF equivalent
Breaks
Secret Topics
Silently excluded from export if admin or Slab Bot lacks access
Breaks
Requires Engineering
Authorship
Confluence labels all imported pages as created by the importing user
Needs Work
Code Block Language Tags
ADF language tag format differs — edge cases like tsx and hcl need verification
Needs Work
Post Ordering
Must explicitly set page position during creation or ordering is lost
Needs Work
Callout Blocks
Require explicit mapping rules to Confluence panel macros per callout type
Needs Work
Transfers Cleanly
Table Formatting
Simple Markdown tables translate cleanly — complex layouts may break
Clean
Headings & Text
Standard Markdown content converts to ADF without issues

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 Slab and Confluence 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 Slab data and Confluence
  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 Slab or Confluence 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 Slab to Confluence. Can't find what you're looking for? Talk to our team.

Can I import Slab content directly into Confluence?
No. Confluence has no native Slab importer. You can export Markdown from Slab and either use Confluence's space import (limited to 200 MB of uncompressed XML) or build an API-driven pipeline that translates Markdown to Atlassian Document Format (ADF) and creates pages via the Confluence REST API. Pushing raw HTML through the v1 API lands pages in the legacy editor, which Atlassian is fully deprecating in April 2026.
Does Slab have an API for migration?
Yes, Slab offers a GraphQL API, but it's only available on Business or Enterprise plans. The API returns content based on what the Slab Bot user has access to — secret topics and drafts are excluded unless Slab Bot is explicitly granted access.
How do I preserve internal links when migrating from Slab to Confluence?
Build a link-mapping table during migration. First, import all pages to generate new Confluence Page IDs. Then build a mapping table linking old Slab URLs to the new IDs. Finally, run a second pass through every page's ADF body, replacing Slab URLs with the corresponding Confluence page links.
What is the Confluence Cloud XML import size limit?
Confluence Cloud enforces a strict 200 MB limit on the uncompressed entities.xml file inside the import archive. Attachments don't count toward this limit, but page content, history, and metadata do. Spaces exceeding 200 MB must be migrated via the REST API instead.
Will Slab comments and embeds survive the migration?
Usually not cleanly. Slab's post comments are absent from the standard export and not reliably available via the API for mapping to Confluence's inline comment system. Embedded integrations (GitHub previews, Figma frames, Loom videos) migrate as plain URLs since Confluence does not support iframe content in ADF.
How long does the Slab to Confluence 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 Slab 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 Slab to Confluence?
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.
