When this migration is needed
- Public/finance deals require in-country data residency
- Notion fails security review (no on-prem option)
- Need Korean approval workflow
- Cost optimization (leverage Dooray free tier)
Prep (1 week)
1. Back up all Notion pages/DBs (Workspace Settings → Export) 2. Create Dooray account + design project/wiki structure 3. Set migration priority: wiki → projects → tasks
The actual move (2–4 weeks)
Docs / wiki Export Notion pages (HTML/Markdown) → manually copy into Dooray Wiki. Block structures don't map perfectly — reorganize after copy.
Databases / tasks Notion DB → CSV export → manual import to Dooray projects/issues. Field mapping requires thought.
Link cleanup Replace internal links one by one with new URLs. Hard to automate.
Post-migration (1-month overlap)
1. Run Notion and Dooray in parallel for a month 2. New work in Dooray, old references in Notion 3. Gather team feedback, then cancel Notion
Common pitfalls
- Trying for perfect block style replication: impossible. Reorganize
- Canceling Notion first: permanent data loss risk
- Not designing approval flow in advance: misses Dooray's strength
Typically 1–2 months for teams under 20.
