Windows Server 2012R2 Migration Guide for ShareFile storage zones


Microsoft is ending support for Windows Server 2012R2 on October 10, 2023. It is important to migrate your server to a newer version before the end of support date.

This article provides guidance on how to migrate your ShareFile Storage Zone server from Windows Server 2012R2 to a newer version.

To migrate to a newer version of Windows Server, you must add a secondary storage zone controller to the new server and then promote it as the primary controller.

System requirements

The Storage Zones Controller Server supports the following versions:

  • Windows Server 2016
  • Windows Server 2019
  • Windows Server 2022



The following steps DO NOT cover migrating the ShareFile Data Repository. If you have the ShareFile Data Repository on the same server as the storage zone controller you are planning to migrate or have a storage zone data repository on a File Server running Windows Server 2012R2 to migrate, see Transfer files to a new network share for more information.

Step 1 - Prepare the new server for the ShareFile Storage Zone Controller

Prepare the new server using the steps provided in Prepare your server for ShareFile data.

Step 2 - Install the Storage Zone Controller on the new server and add it as Secondary

After preparing the new server for ShareFile, you need to add it to the storage zone as a secondary server. See Join a secondary storage zones controller to a storage zone for more information.

Step 3 - Promote the new server to Primary, demote the old server to Secondary

After adding the new server as secondary, the next step is to promote it to primary. The older server must also be demoted to secondary. For more information on this step, see Demote and promote storage zones controllers.


ShareFile recommends that you test the functionality of the new storage zone server on its own, without using the older server as a secondary. You can do this by temporarily disabling the older server. For more information, see To disable a storage zone controller

Step 4 (optional) - Add additional secondary servers

If necessary, for each additional secondary server, return to Step 2 - Install the Storage Zone Controller on the new server and add it as Secondary.

Step 5 (optional) - Update NetScaler service group members

If you have a NetScaler, ensure the new storage zone servers are added to the ShareFile service group. See To add members to a service group by using the configuration utility for more information.

Step 6 - Delete the old storage zone controller server from the ShareFile Admin Portal

Once the Storage Zone servers have successfully migrated, the older servers can be deleted from the ShareFile Admin Portal. See To delete a storage zones controller for more information.
