The license file (extendsim.lic) on the License Server needs to be updated and reactivated whenever there is this type of change to the license. After we notify you that the change has been made and the license has been updated, you will need to reactivate the License Manager. However, you do not need to send new license files to Client devices. The License Manager automatically updates the license files on Client devices. See the document titled Reactivating ExtendSim Floating Licenses.
