When migrating file servers to SharePoint and Teams, chaotic structures become expensive, ongoing construction sites. The result: rising operating costs, difficult-to-manage permissions, and user frustration. migRaven.Analyzer delivers the necessary analytics-first strategy and combines on-premises and cloud into a unified analytics platform.
Focus on security
Effective permissions and external access are finally transparent. The analyzer reads permissions at the site, library, folder, and file level, resolves Entra ID groups and roles (including Microsoft 365 Groups/Teams) down to the user, and recognizes guests (userType = Guest). Externally shared content – including the type of release and the person who created it – is specifically identified.
Cost control & structural governance
Keep data growth, versioning, and storage trends under control. The analyzer aggregates file types, number, age, and size per area and identifies data owners. The storage cost report (configurable €/GB rate) and trend reports let you actively counteract this.
Foundation for file server to cloud migration:
Identify obsolete/unused data (typically 30–50% of data) and reduce migration volume and costs (up to 50%). Blockers such as path length limits (255/400 characters) or unsuitable file types become visible early. In combination with migRaven.one Tasks (deletion, archiving, migration) can be delegated directly to data owners and controlled centrally.
Note: Values are typical project results and may vary.
Feature details
1. Security & Release Analysis
More visibility for rights & shares: Complete readout of effective permissions in SharePoint & Teams, including resolution of groups and roles down to the user level and clear labeling of external access.
- Effective permissions: Evaluation at site, library, folder and file levels.
- Group & role resolution: Resolution of Entra groups/roles and M365/Teams groups down to the user.
- Hybrid transparency: Compare cloud accounts with on-premises AD for consistent reporting.
- External sharing at a glance: Clearly identify guests and anonymous links; list external content with sharing type and responsible party.
2. Costs, Trends & Ownership
Governance & Cost Control: Structural insights from sites and libraries to folders and files. Aggregated metrics on types, counts, age, and size per area – ideal for cleanup and control.
- Structure Insights: Capture the hierarchy of sites → libraries → folders → files.
- Data profile: Aggregation of file types, count, age and size per area.
- Data Owner per area: Derivation of a responsible person per folder or data room.
- Cost & Trend Reports: Estimate storage costs per site/team and track storage trends over time.
3. Migration enablement (file server → M365)
Foundation for a lean migration: Identification of obsolete or unused data, early detection of typical showstoppers and seamless task management in conjunction with migRaven.one.
- Data reduction upfront: Reliably identify unused and obsolete data and reduce its volume.
- Detect showstoppers early: Make path length limitations and unsuitable file types visible in a timely manner.
- Project management: Delegate tasks such as deletion, archiving or migration to data owners and orchestrate them centrally.
