Authors and timestamp system properties will not be preserved after the migration

Symptoms

When attempting to migrate documents and/or list items, Sharegate signals that the authors and timestamps system properties (Created, Created By, Modified and Modified By) will not be preserved after the migration.

Error code

Details

Under certain conditions, SharePoint does not offer services for client applications such as Sharegate to be able to set specific system properties. The result is that Sharegate cannot preserve the information about the authors and timestamps unless you download the server extension in the destination server of your migration.

Solution

If you need the server extension:

Download and install the server extension (which can be found here) on your destination SharePoint server. Sharegate will then use this extension to preserve those properties. To get more information about the server extension, you can check our documentation here.
