Move Beyond Lotus Notes and Domino
01
Can’t find or afford Domino administrators anymore?
02
Notes applications that nobody understands but everyone depends on?
03
Email on Notes while everyone else is on Outlook and Teams?
Tried migrating before but the custom applications stopped you?
What We Do
A Complete Path Off Lotus Notes
01
The complete exit — not just email
We migrate email AND the custom applications, workflows, and documents that keep organisations trapped on Notes.
02
We know both platforms
We understand Notes/Domino structure (NSF databases, agents, views, forms) AND Microsoft 365 — so nothing falls through the gap.
03
Applications assessed, not overlooked
Every Notes application is assessed and classified for rebuild, migration, archive, or retirement with business-owner input.
Email migrated with fidelity
We migrate email, calendar, contacts, and archives with high fidelity — preserving history, attachments, and folder structure.
05
Documents to SharePoint/OneDrive
We migrate Notes document databases to SharePoint and OneDrive with metadata, permissions, and structure preserved.
06
Users landed on modern M365
We don’t just move data — we land your team on Teams, SharePoint, OneDrive, and Outlook with training and adoption support.
Our Services & Capabilities
What We Migrate
01

Already on M365 but need SharePoint migration help?

Our Notes Migration Methodology
Free consultation & discovery
We discuss your Notes/Domino environment, timeline, and concerns — and give you an honest view of scope and complexity. No cost, no obligation.
Full environment inventory
We inventory every mailbox, NSF database, application, document store, and integration — the complete picture most migration firms skip.
Application assessment (the critical step)
We assess every Notes application with its business owner: rebuild on Power Apps/SharePoint, migrate data, archive, or retire. This step prevents the “we forgot about that app” disasters.
Email & calendar migration
We migrate email, calendar, contacts, and archives to Exchange Online — typically in waves, with coexistence during the transition.
Application rebuild & document migration
We rebuild critical applications on Power Apps/SharePoint and migrate documents with metadata and permissions.
User adoption & training
We train users on Outlook, Teams, SharePoint, and OneDrive — and support the transition from Notes habits to M365 workflows.
Domino decommission
Once everything is migrated and validated, we plan and execute the Domino server decommission — a clean exit.
It starts with a free Notes migration assessment. No obligation.

Case Studies
Manufacturing company, 400+ users, 60+ Notes applications.
Domino → Exchange Online, Notes apps → Power Apps/SharePoint, documents → SharePoint
20 years on Notes with 60+ custom applications — two previous migration attempts had stalled on the apps.
Inventoried all 60 apps, assessed with business owners (30 rebuilt, 15 archived, 15 retired), migrated email, and trained users.
Financial services firm, 250+ users, compliance archives.
Domino → Exchange Online, archives → Exchange Online Archive
Email migration needed to preserve 10+ years of compliance archives with full fidelity.
Migrated all mailboxes and archives to Exchange Online with folder structure, attachments, and timestamps intact.
Professional services firm, 150+ users, 25+ Notes applications.
Notes apps → Power Apps + Power Automate + SharePoint
Critical business processes ran on Notes applications that nobody could maintain — but everyone depended on.
Assessed all 25 apps, rebuilt the 12 critical ones on Power Apps with Power Automate workflows, and archived the rest.

Insights
Every Year You Stay on Notes Gets Harder (2026)
In 2026, many organisations still on Lotus Notes, now HCL Notes/Domino, are reassessing the cost and risk of staying there. The pressure usually comes from a shrinking administrator pool, ageing infrastructure, user expectations around Outlook, Teams and Microsoft 365, and the growing complexity of undocumented NSF applications. The longer the environment remains unchanged, the more important it becomes to inventory applications and plan migration in phases.
01
Talent vanishing — Notes/Domino administrators are retiring; the talent pool isn’t being replenished
02
03
The app problem doesn't go away
Custom Notes applications are usually the hardest part of a Notes migration. We inventory each NSF application, review usage and business ownership, and decide whether it should be rebuilt on Power Apps, Power Automate or SharePoint, migrated as data, archived, or retired. The goal is a maintainable Microsoft 365 environment rather than a direct copy of legacy Notes applications.
Frequently Asked Questions
What do your Lotus Notes to Microsoft 365 migration services cover?
We cover the complete Notes/Domino exit: email and calendar migration to Exchange Online, Notes application assessment and rebuild on Power Apps/SharePoint, document database migration to SharePoint/OneDrive, user adoption and training, and Domino server decommission. The full exit, not just email.
Can you migrate our custom Notes applications, not just email?
Yes — and this is our key differentiator. We inventory every NSF database, assess each with its business owner, and rebuild critical ones on Power Apps and SharePoint. For large Notes estates, we handle application portfolios through inventory, complexity scoring and rebuild, archive or retire decisions.
Will we lose any email history or attachments?
No — high-fidelity email migration preserves folder structure, attachments, timestamps, and read/unread status. We validate migration completeness before cutover. For compliance-sensitive environments, archives are migrated with full integrity.
How do you decide which Notes apps to rebuild vs retire?
We assess each application with its business owner using four categories: Rebuild (critical, actively used — rebuild on Power Apps/SharePoint), Migrate (data needed but app not — move data only), Archive (no longer active but needed for reference), Retire (obsolete — document and decommission). The business owner decides; we execute.
How long does a Notes to M365 migration take?
It depends on volume and application complexity. A 50-mailbox email-only migration runs 2–4 weeks. A 250-mailbox migration with 20+ applications runs 2–4 months. A 500+ user full exit with 50+ applications runs 4–8 months. The application assessment and rebuild is always the longest stream.
How much does a Notes to M365 migration cost?
It depends on mailbox count, application complexity, document volume, coexistence needs and the number of applications that must be rebuilt or retired. The estimator uses an indicative $400–$600/day range; a consultation confirms the scope, timeline and fixed migration plan.
Can we run Notes and M365 side by side during migration?
What if we tried to migrate before and it failed?
We hear this regularly — and the blocker is often the custom applications. Email migration may move mailboxes, but organisations can remain dependent on Domino if apps, workflows and document databases are not assessed. Our approach covers both the data migration and the application transition.
