Introduction
Modernize Your Email Infrastructure
Cloudiway provides enterprise-grade migration of mail databases from IBM Lotus Notes/Domino to Microsoft 365, preserving emails, calendars, contacts, and tasks.
IBM Lotus Notes and Domino served organizations well for decades, but the shift to cloud-based collaboration platforms like Microsoft 365 offers significant advantages in terms of functionality, accessibility, and cost-effectiveness.
Migrating mail databases from Lotus Notes presents unique technical challenges due to its proprietary NSF format and distinctive data model. Cloudiway's proven migration platform addresses these challenges, ensuring a seamless transition to Microsoft 365 with zero data loss.
Why Migrate from Lotus Notes to Microsoft 365
Organizations are moving away from Lotus Notes/Domino for several compelling reasons:
- End of Life Concerns: IBM's shift away from Notes means declining support and development
- Cloud-First Strategy: Microsoft 365 provides modern cloud collaboration with global accessibility
- Cost Optimization: Eliminate on-premises infrastructure and reduce IT overhead
- Modern User Experience: Outlook and Teams offer intuitive interfaces users expect
- Integration Ecosystem: Seamless integration with thousands of business applications
- Advanced Security: Enterprise-grade security with AI-powered threat protection
- Mobile Productivity: Full-featured mobile apps for iOS and Android
Microsoft 365 Advantages
- Collaboration: Teams, SharePoint, and OneDrive for modern teamwork
- Scalability: Easily scale from tens to thousands of users
- Compliance: Built-in compliance tools for industry regulations
- AI-Powered: Copilot and intelligent features enhance productivity
What Gets Migrated from Lotus Notes
Cloudiway ensures comprehensive migration of all your Lotus Notes data:
Important: Mail Databases Only
Cloudiway migrates Lotus Notes mail databases (NSF) only. Custom Notes applications, workflows, and databases with custom forms are not supported. These require separate modernization projects using Microsoft 365 tools like SharePoint, Power Apps, or Power Automate.
Lotus Notes Migration Challenges
Migrating from Lotus Notes to Microsoft 365 presents several technical hurdles:
NSF Database Format
Lotus Notes uses proprietary NSF files requiring specialized extraction tools to access emails, calendar data, and documents.
Rich Text Formatting
Lotus Notes rich text format differs from HTML and must be carefully converted to preserve email formatting, embedded objects, and inline images.
Time Zone Handling
Calendar entries must be correctly converted between Notes time zone format and Exchange Online to prevent scheduling conflicts.
Data Volume & Performance
Large NSF files and extensive mail archives require optimized migration processes to complete within acceptable timeframes.
The Cloudiway Solution
Cloudiway's Lotus Notes migration platform provides comprehensive capabilities specifically designed for Notes to Microsoft 365 migrations:
Direct NSF to Exchange Migration
Native NSF file processing extracts emails, calendars, contacts, and tasks directly from Notes databases with complete metadata preservation.
Rich Text Conversion
Advanced rich text processing preserves email formatting, tables, embedded images, and document links during conversion to HTML format.
Intelligent Calendar Conversion
Accurate time zone conversion, recurring event handling, and meeting participant mapping ensure calendar integrity.
Delta Sync & Coexistence
Incremental synchronization allows users to continue working in Notes while migration progresses, minimizing business disruption.
Batch Processing & Automation
Migrate hundreds of mailboxes simultaneously with automated error handling, retry logic, and detailed progress reporting.
24x5 Expert Support
Dedicated migration specialists provide guidance throughout your project, from planning to post-migration validation.
The Lotus Notes to Microsoft 365 Migration Process
Our proven methodology ensures successful migration with minimal risk and business disruption:
Discovery & Planning
Analyze your Lotus Notes environment, identify mailbox sizes and archives, and create a detailed migration plan.
Prepare Environments
Set up Microsoft 365 tenant, create user accounts, configure authentication, and prepare Domino server access.
Pilot Migration
Migrate a small group of test users to validate settings, verify data integrity, and identify any issues before full deployment.
Batch Migration
Execute migration in planned waves, processing multiple users in parallel while monitoring progress in real-time.
Verification & Cutover
Verify data integrity, perform delta sync to capture final changes, and complete cutover to Microsoft 365.
Best Practices for Lotus Notes Migration
Follow these proven best practices to ensure migration success:
Conduct Comprehensive Discovery
Inventory all Notes mail databases and archives. Identify active users, mailbox sizes, and any special mailbox configurations that require attention during migration.
Archive or Purge Old Data
Reduce migration scope by archiving historical data that users don't need immediate access to. This speeds up migration and reduces Microsoft 365 storage costs.
Handle Archives Properly
Include archived mail databases in your migration scope. Plan whether archives should migrate to user mailboxes, archive mailboxes, or remain accessible via alternative methods.
Run Pilot Migrations
Select a diverse pilot group representing different departments, mailbox sizes, and application usage. Validate all migration aspects before proceeding with full deployment.
Provide User Training
Lotus Notes and Outlook have different interfaces and workflows. Provide training materials and support to help users adapt to Microsoft 365 quickly and maintain productivity.
Plan for Coexistence Period
Allow for a coexistence period where some users remain on Notes while others move to Microsoft 365. Ensure email routing and calendar free/busy lookup work across both platforms.
Verify Data Integrity
Use Cloudiway's built-in verification reports to confirm all data migrated successfully. Spot-check critical folders, calendar entries, and contacts for accuracy before decommissioning Notes.

Frequently Asked Questions
Can Lotus Notes NSF files be migrated to Microsoft 365?
Yes, Cloudiway fully supports migrating Lotus Notes NSF files to Microsoft 365. The migration includes emails, calendar entries, contacts, tasks, journal entries, and notes. All folder structures and metadata are preserved during the migration to Exchange Online mailboxes.
Does Cloudiway migrate Lotus Notes applications?
No, Cloudiway specializes in mail database migration only. Lotus Notes applications (NSF databases with custom forms and workflows) are not supported. Cloudiway focuses on migrating mailboxes, calendars, contacts, and tasks from Notes mail databases to Microsoft 365.
How long does a Lotus Notes to Microsoft 365 migration take?
Migration duration depends on mailbox size, number of users, and data volume. A typical user with a 5GB mailbox migrates in 4-8 hours. For enterprise migrations with hundreds of users, Cloudiway processes multiple mailboxes in parallel. Most organizations complete their migration within 2-4 weeks including planning and testing.
Are calendar entries and meeting invitations preserved?
Yes, Cloudiway preserves all calendar entries, recurring meetings, and meeting invitations from Lotus Notes. Calendar items are migrated to Outlook/Exchange Online with complete metadata including attendees, recurrence patterns, reminders, and attachments. Time zones are automatically adjusted to prevent scheduling conflicts.
Can we migrate from an on-premises Domino server?
Yes, Cloudiway supports migration from both on-premises IBM Domino servers and cloud-hosted Lotus Notes environments. For on-premises servers, you'll need to provide network access or install the Cloudiway connector. We support all modern Domino versions including 8.5, 9.x, 10.x, and 11.x.
What about email encryption and security during migration?
Cloudiway uses enterprise-grade security for all migrations. Data is encrypted in transit using TLS 1.2+ and at rest using AES-256 encryption. We support OAuth 2.0 authentication and comply with GDPR, HIPAA, and SOC 2 requirements. Encrypted emails are migrated with their original encryption intact where possible.
Do you support incremental migrations for Lotus Notes?
Yes, Cloudiway supports incremental migrations allowing users to continue working in Lotus Notes while migration is in progress. Delta sync ensures new emails and calendar changes are captured and migrated. This enables a phased migration approach with minimal disruption to business operations.
