reference project Sharepoint migration
for 24.000 employees and 2,4 PB of data

The project involved migrating the entire directory structure of 24.000 employees, 12.000 DFS links and 48.000 directories with explicit permissions, as well as 2,4 PB of data to SharePoint O365. There were complex challenges: a deeply structured initial structure with authorizations up to the fourth level, a high proportion of old data and some outdated data owner information. Additionally, the structure was not compliant with SharePoint migration guidelines.

The solution was to eliminate 70% of irrelevant directories using the migRaven.24/7 Identify analyzers, redefine data owners accordingly and prepare the migration with the Linkfixer tool. The implementation was carried out by migRaven.one, whereby the application directories were also migrated to a new local file server structure.

The project duration was 18 months.

Project

• Employees: 24.000
• DFS Links: 12.000 - 48.000 directories with expl. Permissions
• Data: 2,4PB
• Complex initial structure
• Outdated data
• Outdated data ownership
• Policy compliance - i.eThe initial structure did not meet the requirements for a direct migration to SharePoint

challenges

• Initial structure deeply structured with authorizations up to the 4th level
• High proportion of old data
• DataOwer for directories were sometimes no longer up to date
• Initial structure did not meet the guidelines for direct migration to SharePoint

Limitations

First level permissions only; Unsupported file types; more than 100K files in individual directories

Solution

• Irrelevant directories with migRaven.24/7 Analyzer determined (rate 70%)
• Data owner about migRaven.24/7 Analyzer calculated
• Prepare the structures for migration with Linkfixer (Linkfixer/ migRaven.one)
• Complete project management via migRaven.one carried out
• structure over migRaven.one migrated to SharePoint
• Application directories migrated to new local file server structure

Project duration

18 months

Tools used

• migRaven.24/7 Analyzer
