Removal of Legacy Components
The following information is only relevant to Mercury System Admins of organisations who are using bespoke customisations.
Occasionally it is necessary for legacy components to be removed in order to improve performance across the Mercury Platform. Before the decision is made to remove these, we conduct investigation to assess the impact.
The majority of customers will not see any impact at all in these components being removed however a small number of customers who have created bespoke customisations that call on one of these components may notice a change.
For a list of permitted customisations please refer to this document.
Going forwards we will give you notice of at least 1 release of any components that are slated for removal, and we encourage you to raise a support ticket if you have any questions relating to the removal of the particular component.
The component listed below is scheduled for deletion in Release v37 of Mercury, currently scheduled for April 2026.

How to identify dependencies on Legacy X DNU Components
