This topic describes the Mirroring feature in Episerver CMS.
Note: Mirroring is not supported on Episerver Digital Experience Cloud (DXC) and other cloud deployments. Mirroring is a legacy feature that will be removed in future versions.
Mirroring lets you maintain content in one location and push the content to other sites by scheduling export/import of selected CMS data from one site to another. The Episerver CMS administration interface lets you manage mirroring rules and associated batch jobs. Mirroring keeps track of pages that are moved and deleted, maintaining the exact page structure.
The following objects are included in mirroring:
Note: You can install mirroring only on Episerver CMS 7.5 (through the Deployment Center). If you want mirroring with the latest Episerver version, install a CMS 7.5 site with mirroring, and then upgrade to the latest CMS through NuGet because there is no NuGet package for mirroring functionality; it is installed as a separate service in a virtual directory on the server.
Note: An updated DLL is available in the EPiServer.CMS.Core NuGet package (packages/EPiServer.CMS.Core.9.0.0/tools/MirroringService/), which you must manually patch when upgrading.
Note: Episerver CMO and Episerver Commerce do not support mirroring.
You can manage export of templates between sites through XCOPY deployment. See Deploying to Windows Servers.
Even though two-way mirroring is possible, the mirroring service is configured as one-way-mirroring; the mirroring service sends the content to another service. In Episerver CMS, the mirroring service detects whether the content was previously mirrored, so if you run a mirroring job many times without changing of the content, the content on the target site is ignored and unchanged.
