When to consider migration
Triggers for switching from global SaaS to Korean alternatives: (1) Korean customer support becomes the main workload, (2) e-tax invoice / KRW billing burden spikes, (3) per-seat cost of global tools escalates with team growth.
Migration sequence (low-risk first)
1. Email marketing (low risk) Mailchimp → Stibee. CSV contact export + template rewrite. 1–2 weeks.
2. Customer support (medium risk) Intercom/Zendesk → Channel.io. Conversation history often can't migrate — export closed tickets only and start fresh in Channel.io.
3. Payments / invoicing (medium risk) Stripe → PortOne (I'mport) or TossPayments. Careful with subscription migration; switch new customers first.
4. Project / docs (medium risk) Asana/Monday → Dooray. Keep Notion if it still fits.
5. CRM (high risk) HubSpot → Dabinci/Zoho. Full deal/contact migration + automation rewrite. 1–2 months.
6. HR (high risk + rewrite) BambooHR → Flex. Data structures differ — careful field mapping required.
Checklist
- [ ] **Data export availability**: check every global SaaS upfront
- [ ] **Automation rewrite**: update n8n / Make scenarios
- [ ] **Email signatures / links**: reflect new URLs
- [ ] **Customer communication**: announce support channel changes 2+ weeks in advance
- [ ] **Parallel operation**: run both systems simultaneously for at least 1 month
Common mistakes
- Migrating everything at once: can't handle customer inquiry spikes
- Canceling contracts before data export: unrecoverable
- Skipping automation rewrite: leads drop out
Order summary
1. Email → 2. Support → 3. Payments → 4. Project/docs → 5. CRM → 6. HR
Observe for 1–2 weeks at each step before the next. Don't rush — protect the customer journey.
