Description:
 def updateLicenseManager(self, licenseManagerInfo):
 """ ArcGIS License Server Administrator works with your portal and enforces licenses for ArcGIS Pro. This operation allows you to change the license server connection information for your portal. When you import entitlements into portal using the Import Entitlements operation, a license server is automatically configured for you. If your license server changes after the entitlements have been imported, you only need to change the license server connection information. You can register a backup license manager for high availability of your licensing portal. When configuring a backup license manager, you need to make sure that the backup license manager has been authorized with the same organizational entitlements. After configuring the backup license manager, Portal for ArcGIS is restarted automatically. When the restart completes, the portal is configured with the backup license server you specified. Parameters: licenseManagerInfo - The JSON representation of the license server connection information. """
