## SharePoint Migration and Document Sovereignty: a transformation that goes beyond a simple file transfer 

At CEO-Vision, **a SharePoint migration project is not just about copying and pasting files**. It is a **comprehensive and structured approach** that incorporates **technical**, **organizational**, and **document governance** challenges.

## A comprehensive and proven migration methodology 

The projects carried out rely on a structured approach including:

- analysis of the **SharePoint information architecture**
- analysis of **metadata** and **structured transfer into the Alfresco ECM**
- adaptation of **migration tools specifically developed over the course of projects**
- **estimation** of **migration timelines** (initial and delta)
- execution of **test migrations**
- **document integrity checks** between source and target
- **user change management support**

This approach makes it possible to **handle complex environments**, such as **recovering documents from systems like SEDIT** (historical links to SharePoint) and their **migration to GoFAST / Alfresco** in a production environment, **without disruption for users**.

## SharePoint 2016 and 2019: end of support in July 2026 

The message is clear: **Microsoft will end support for SharePoint 2016 and 2019 in July 2026**. This deadline comes with an **acceleration toward Microsoft 365 in SaaS mode**.

For organizations still running **on-premise SharePoint**, this implies a transition **to SaaS solutions subject to extraterritorial laws such as the Cloud Act**, with data potentially accessible regardless of the datacenter location.

This evolution also creates significant constraints for organizations, including:

- increased **dependency** on **SaaS models**
- known **limitations** with **large document volumes**
- **constraints** related to **complex folder structures**
- gradual **removal** of traditional **standalone SharePoint plans**

## A sovereign alternative based on Alfresco 

In this context, **GoFAST** positions itself as a **sovereign alternative to SharePoint, based on Alfresco as its ECM foundation**.

The solution includes a range of collaborative and document management features:

- **business workflows** (BPM Bonita)
- **collaborative editing** (OnlyOffice)
- **video conferencing** (Jitsi)
- **secure chat** (Element / Matrix)
- **legally binding electronic signature** integrated into workflows
- **search and indexing engine** (Apache Solr) with full-text extraction
- **advanced security features** (document classification, granular permissions management, secure email sharing)
- **sensitivity level management** (C3 / EUCS / TLP)

It also enables **multi-use access** with **granular permissions management** and **full technical administration**.

- **National regulator**: migration including C3 Confidential classified documents

## A deadline that becomes an opportunity 

**The 2026 deadline is a major milestone for organizations**. It offers the opportunity to **regain control over their data and costs**, while rethinking their document environments with a focus on **sovereignty** and **business continuity**.
