ProActive have been assisting COWI with many projects related to modernisation of the way COWI works with projects leveraging multiple services from Microsoft 365. One of those was the migration of COWI’s on-premise Exchange environment to Microsoft 365.
For many years, COWI relied heavily on the use of used Exchange Public Folders to store large amounts of data. With a total data amount of 20 TB data in 32 million emails COWI garnered the title of Europe’s largest public folder environment.
However, given Microsoft’s ongoing phasing out of the public folder system, COWI has been forced to find an alternative solution to their data storage. This, combined with a desire to reduce operating costs and at the same time start working in the cloud, led to the decision to migrate from on-premises Public Folders to Microsoft 365.
Planning for increased migration capacity with BitTitan
ProActive has been the executive party in the phasing out of public folders as well as the migration to the new Office 365 Groups and SharePoint.
When it came to tooling, the ProActive team evaluated a first-party public folder solution from Microsoft. It quickly became apparent COWI’s Public Folder environment was too large for Microsoft’s own migration tool to handle the entire project. However, ProActive engaged with BitTitan and their MigrationWiz solution, which in early tests proved to handle a much greater capacity than the first-party tool and reached data transfer goals for the migration.
