Symptoms
When doing a pre-check or when copying objects, one of the following messages is displayed:
User alerts cannot be migrated from SharePoint 2003.
Error code
AN-052-032
AN-053-032
AN-055-032
Details
The Server Extension is required for the migration of user alerts. Since the Server Extension is not compatible with SharePoint 2003, ShareGate Migrate is unable to copy user alerts from SharePoint 2003.
Note: As of November 2021, ShareGate Migrate is no longer able to provide full support for SharePoint Server 2003 and 2007, which are past the end of their Microsoft support lifetime. For more information, there is a section about it in the Contact our technical support team article.
