When you want to update a base layer, but the reference machine that was used to create the original base layer is not available, you can recreate the original reference machine from the existing base layer.


In the Horizon Mirage Management console, expand the Image Composer node and select the Base Layers tab.


Right-click the base layer and select Create Reference CVD from layer.

Click Finish.

Use a Horizon Mirage Restore operation to download and apply the image of the original reference machine to a selected device to serve as a new reference machine. See Restoring to a CVD After Hard Drive Replacement or Device Loss. You then update or install core applications and apply security updates on the new reference machine before you capture a new base layer using the existing reference CVD.
