Upgrading to later New York or Orlando patches causes a Skipped Error in the upgrade history for the system property glide.import.file.extension_whitelist [sys_properties_ba189b005b001010953330ad5981c755]Description When upgrading to later New York or Orlando patches, once the upgrade has completed, a Skipped Error is reported in the Upgrade History for the XML record sys_properties_ba189b005b001010953330ad5981c755, which is for the system property glide.import.file.extension_whitelist.Steps to Reproduce 1. Use any out-of-box instance running on early New York or early Orlando.2. Upgrade the instance to New York Patch 9 or Orlando Patch 4.3. In the Upgrade History, see the following Skipped Error for the XML record [sys_properties_ba189b005b001010953330ad5981c755] for the Skipped Changes to Review. Workaround This problem has been fixed. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to. The Skipped Error can be safely ignored. It is due to the system trying to create the sys_properties record, but failing due to glide.import.file.extension_whitelist being in the glide.properties file in the glide.properties.blacklist list. The system will always set the default values from the backend source code, even if the property does not exist on the instance. The default values in New York are csv,xls,xlsx,json,xml,zip,xlsm and in Orlando and above csv,xls,xlsx,json,xml,zip,txt. xlsm is only needed and used in New York. The system property is type "string" and the write roles are maint. The description is - "A case-insensitive, comma-separated list of extensions that are allowed when using DataSource.createAttachedDataSource(). For security reasons DO NOT ALLOW the war extension."If you wanted to create this system property, a maint user would have to create it manually with the values, type, and description specified above.Related Problem: PRB1413065
