Cloud & SharePoint Migration
Modernize legacy SharePoint environments, migrate business content to Microsoft 365, and move critical applications, workflows, documents, and collaboration solutions to a supported technology platform.
Moving SharePoint Is More Than Copying Files
A successful SharePoint migration requires understanding the existing environment before moving anything.
Sites may contain custom lists, libraries, permissions, workflows, forms, web parts, metadata, business rules, JavaScript, legacy components, and integrations that need to be evaluated before they can be moved or modernized.
Bellevue Coders approaches migration as both a technical project and a business process modernization effort.
Modern SharePoint Solutions
Migrate legacy content while identifying opportunities to replace older workflows and customizations with supported Microsoft 365 technologies.
Where We Can Help
Every migration is different. Bellevue Coders can support individual phases of a migration or assist throughout the full modernization lifecycle.
SharePoint Migration
Assess and migrate SharePoint sites, document libraries, lists, metadata, permissions, and business content.
Microsoft 365
Move legacy collaboration environments toward SharePoint Online and Microsoft 365 services.
Workflow Modernization
Evaluate older SharePoint and SharePoint Designer workflows and identify supported modernization paths.
Content Migration
Move documents, libraries, metadata, lists, permissions, and structured business information.
Application Modernization
Rebuild or replace legacy forms, JavaScript, web parts, workflows, and business applications.
On-Premises Modernization
Evaluate supported migration paths for organizations that must maintain SharePoint Server environments.
A Structured Migration Process
Successful migrations begin with discovery and assessment, not with the migration button.
Start by understanding what exists today and where the organization wants to go.
- Inventory SharePoint sites and solutions
- Identify site owners and business stakeholders
- Review document libraries and lists
- Identify custom forms and web parts
- Document workflows and integrations
- Identify obsolete or unused content
- Define the destination architecture
Scan the environment to identify content and components that may require remediation before migration.
- Run migration assessment tools
- Review unsupported components
- Identify large files and libraries
- Review permissions and security groups
- Analyze workflows and customizations
- Remove unnecessary content
- Develop remediation plans
Configure the destination before moving production content.
- Create destination sites
- Configure information architecture
- Create required security groups
- Configure permissions
- Prepare metadata and content types
- Prepare Microsoft 365 services
- Establish migration test environments
Perform controlled migration waves rather than attempting to move everything at once.
- Run pilot migrations
- Validate migration mappings
- Move sites, libraries, lists, and content
- Preserve appropriate metadata
- Perform incremental migration passes
- Coordinate cutover windows
- Document migration results
A migration is not complete simply because content copied successfully.
- Validate content
- Test permissions
- Test business processes
- Validate forms and workflows
- Conduct user acceptance testing
- Train users when necessary
- Document the new environment

SharePoint modernization experience involving legacy enterprise solutions and multiple generations of Microsoft SharePoint.
SharePoint 2010 → SharePoint 2019 Migration
The Environment
Legacy SharePoint solutions originally developed for earlier SharePoint environments needed to be evaluated, migrated, modernized, and validated for SharePoint 2019.
Migration Work
- SharePoint 2010 solution review
- SharePoint application migration
- Legacy page and solution modernization
- Compatibility analysis
- JavaScript and interface updates
- Testing and validation
Modernization Goal
Preserve the business purpose of established applications while moving the solutions to a newer supported SharePoint architecture.
Experience migrating working business solutions across major SharePoint generations provides practical insight into the challenges of modernizing legacy enterprise applications.
Migration Experience Beyond File Copying
Development Experience
We understand that legacy SharePoint environments often contain code, workflows, forms, scripts, and business applications.
Microsoft Technologies
Microsoft 365, SharePoint, workflow technologies, web development, and enterprise application experience.
Project Management
Migration requires planning, testing, communication, documentation, sequencing, and controlled deployment.
B2B Support
Engage Bellevue Coders for a migration project, technical assessment, development support, or additional migration capacity.
Planning a SharePoint or Microsoft 365 Migration?
Start with an assessment of the current environment. We can help identify what should move, what should be modernized, and what should be retired before migration begins.
