Where the dependencies sit
Relations, rollups, formulas, synced content and embedded services can make an apparently simple workspace hard to reconstruct.
Map the work before selecting software
Ask each team which functions are essential, which can change and which can be retired. Separate standard processes from custom logic, and document who owns each decision.
Data that needs a migration decision
Inspect Markdown/HTML and CSV exports, subpages, attachments and relations. A content export is not a functional workspace clone.
Integrations to preserve
Inventory API clients, forms, automations and embedded dashboards; define where each source of truth will live.
Identity and access map
Map page sharing, guest access and team boundaries before creating the target knowledge structure.
Candidate components
| Component | Role | Licence |
|---|---|---|
| BookStack | Knowledge management | MIT |
| OpenProject | Project Management | GPL-3.0 |
| Nextcloud | Collaboration | AGPL-3.0 |
Identity, backup, monitoring and integration design remain part of the architecture. Each component needs its own fit and edition review.
A phased migration path
Discover.
Inventory systems, contracts, data, permissions and business-critical workflows. Record owners and acceptance criteria.Pilot.
Choose a handbook containing attachments and links plus one relational database. Test both reading and updating in the proposed tools.Rehearse.
Time exports and imports. Reconcile record counts, relationships, attachments and reports against the source.Coexist.
Define the source of truth, prevent duplicate writes and monitor the interfaces between old and new systems.Cut over.
Use an agreed change window, decision owner, communication plan and a clear rollback deadline.Operate.
Train users, document recovery and retain required history before retiring the source.
Risks and security considerations
Database relations and automation may require redesign. Keeping Notion for a specialised workflow can be a valid staged decision.
Protect exports and temporary staging data, restrict migration accounts, use encrypted transport and remove temporary access after acceptance.
Rollback and acceptance
Keep a validated source backup and a record of post-cutover writes. Decide whether rollback restores the old system or replays changes, and rehearse that procedure. Business owners must sign off reconciled data and representative workflows before final retirement.
Implementation effort and ongoing care
The initial effort category is High. It is an editorial screening assessment, not a time or cost quotation. A pilot is required to estimate delivery. Plan for patches, monitoring, integration maintenance, backup restoration and user support.
Common questions
Can one application replace the entire platform?
Sometimes the core use case fits one application, but specialised workflows often require several components. Validate feature gaps before committing.
Can we keep parts of the existing system?
Yes. A hybrid or phased approach can reduce disruption when system boundaries and the source of truth are explicit.
Will open source cost less?
It depends on licensing, migration, infrastructure and operating costs. Compare the same planning period using realistic inputs.
Sources and verification
Policies and features can change. Verify the current terms and your installed edition before implementation.
