TwinCAT license transfer in case of image change

To transfer an existing license to a new image during an image change, you can use the TwinCAT 3 license transfer function. The function is only available for BST version 2.1.x.xx. You can use the TwinCAT 3 license transfer if you want to upgrade or change from one image version to another.

As soon as a backup is restored, the license of the old image is backed up and copied to the new image after the restore, without losing the validity of the license. It is irrelevant for the procedure whether it is a TwinCAT 3 volume license or a normal TwinCAT 3 license.

Proceed as follows:

1. On the start page, click Settings and then click the General tab.
