If the Azure Synapse workspace is removed, Azure SQL DB will stop data replication from landing zone into Azure Synapse. The system stored procedure [sp_change_feed_drop_table_group](/sql/relational-databases/system-stored-procedures/sp-change-feed-drop-table-group) will be called automatically, and the storage account for the landing zone is managed and will be cleaned up automatically.

SQL Server 2022, since landing zone storage account is user managed, data will continue to be published to the landing zone. You should disable the Azure Synapse Link by dropping the relevant table groups with [sp_change_feed_drop_table_group](/sql/relational-databases/system-stored-procedures/sp-change-feed-drop-table-group), and manually remove the storage account for the landing zone.

In SQL Server 2022, the landing zone storage account is user managed. If the landing zone storage account is no longer accessible, and there will be errors in the [sys.dm_change_feed_errors](/sql/relational-databases/system-dynamic-management-views/sys-dm-change-feed-errors). You should disable the Azure Synapse Link by dropping the relevant table groups with [sp_change_feed_drop_table_group](/sql/relational-databases/system-stored-procedures/sp-change-feed-drop-table-group).
