Upgrading to ArcGIS 10.5.1
The copy protection mechanism for ArcGIS Desktop 10.5.1 and ArcGIS Engine 10.5.1 Concurrent Use has been updated. This update requires that ArcGIS License Manager 10.5.1 be installed to support these products.
The ArcGIS License Manager 10.5.1 setup package is designed to detect and upgrade an existing installation of the same product. The existing options file (if applicable) and authorized licenses are retained in the upgrade. Any specific ports present in the service.txt file before the upgrade must be manually reconfigured in the service.txt file following the upgrade to ArcGIS 10.5.1. See the ArcGIS License Manager reference guide for more information on installation upgrades, new installations, or installations over versions earlier than 10.1, which are not supported by the automated process.
Existing ArcGIS 10.1–10.5 authorization numbers will work with ArcGIS 10.5.1.
If ArcGIS License Manager 10.5.1 will be installed on a machine that is different from where an earlier version of ArcGIS License Manager 10.x is currently installed, and you want to use the authorization for ArcGIS License Manager 10.5.1, the earlier version of ArcGIS License Manager 10.x must first be deauthorized before authorizing the ArcGIS 10.5.1 installation.
Obtaining software authorization numbers
If needed, your account's primary maintenance contact can obtain authorization numbers from My Esri . After signing in with your Esri Account, click My Organizations > Products > View Authorizations. Click a product name to obtain its authorization number.
The license version on authorizations eligible for use with ArcGIS 10.5.1 will display as 10.1–10.5.1 under View Authorizations. For those outside the United States, contact your local distributor for information about your authorization numbers.
