+This directory contains samples for the Defer History Data Import APIs. Defer History Data Import is a new
+feature for the upgrade that allows historical data and performance metrics data to be imported in the background
+after the upgrade is done, thus allowing shorter downtime for the whole upgrade process. The feature is only applicable
+for upgrades or migrations from 6.0 and 6.5 with external database. For more information, please review the official
+release notes.
+
+The operations on the API are as follow:
+
+    * status of defer history data import
+    * pause defer history data import
+    * resume defer history data import
+    * cancel defer history data import
+
+Overview of the directory code samples:
+
+    * vc_import_history_sample.py - running a simple workflow to pause and resume
+      Defer History Data Import that is still not completed.
+    * vc_import_history_cli.py - allowing to trigger different parts of the API,
+      showing example code structure.
+    * vc_import_history_common.py - common functionality between the main files.
+
+To view the available command-line options:
+
+     $ python vc_import_history_sample.py --help
+
+     $ python vc_import_history_cli.py --help
+
+Running the samples:
+
+    $ python vc_import_history_sample.py --server <vCenter Server IP> --username <username> --password <password>
+
+Running the cli:
+
+    $ python vc_import_history_cli.py --server <vCenter Server IP> --username <username> --password <password> --operation <operation>
+
+The operation choice is as follows (information is also available using --help)
+
+    * status
+    * pause
+    * resume
+    * cancel
+
+Testbed Requirement:
+
+    * 1 vCenter Server appliance version 6.7 or above successfully upgraded using the option for transferring historical data after upgrade.
