Migrate Local File Server to Cloud

We try to help our customers with a better journey to the cloud and CentreStack is a big piece of that for us. The goal is to provide a super intuitive experience and CentreStack provides easy cloud access with a mapped drive, so there is no learning curve for users like with Dropbox or OneDrive.

File Server Migrations Made Easy!

The Challenge

Traditional file servers can be difficult to access with mobile devices and may need to be periodically replaced at great cost. It’s therefore natural to consider cloud-based options whenever a file server approaches end-of-life. The problem is that cloud migration can be time consuming as users are trained to work with the new platform and administrators have to reconfigure access permissions and folder structures.

The Solution

CentreStack provides a file server agent to synchronize existing file shares, users and permissions to the cloud. Users can continue to use the existing shares until the migration is complete. And once the migration is completed, the file server can be kept as a local gateway or retired to create a cloud-only file access and collaboration platform. The process is so seamless that users generally require no downtime and minimal, if any training.


File Server Migration and Remote Access

The following data flow illustrates the basic architecture and function for this solution.

Step 1

After installing CentreStack, the Cloud Server Agent is installed on the tenants file server and will automatically synchronize file shares, AD users and NTFS folder permissions to the CentreStack installation in the cloud.

Step 2

After login, users automatically get a mapped drive which contains all the shares they have access to, just as if they were on-premises.

Step 3

CentreStack maintains synchronization with the client file server until it has been retired. It remains the primary source for permissions and also acts as an optional proxy to the local domain controller.

Step 4

When a user attempts to open a file on the endpoint, it is downloaded from the backend storage configured for CentreStack and cached locally for fast future access.

Migration Benefits

CentreStack migrates local file servers to a centralized cloud file repository with all the security of traditional file servers combined with cloud based mobile access and secure sharing! And files are stored in the cloud under version control for business continuity.

Seamless Migration

Attach existing shares to cloud storage with no user disruption. Remote users gain instant access during background migration. Existing shares remain untouched for internal use. Easily retire file servers or use them as local gateways.

Access Controls

Use existing AD users and NTFS folder permissions with a simple interface to identify remotely accessible file shares that automatically appear in user's mapped drives


CentreStack allows admins to run HIPAA or GDPR compliancy checks and generate reports demonstrating compliance for file access and collaboration.

Productivity Benefits

Enhanced productivity for remote workers and mobile devices accessing hosted file servers


Mapped drives delay downloads until files are opened and cached locally for fast future access, significantly reducing bandwidth and storage consumption. Users get local performance when working remotely.


Line of business and legacy applications can continue to use the original file shares which remain unchanged.


Minimize user training with a mapped drive that works the same on-premises or remotely. Provide a seamless local experience for users even when they are offline.
