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 a full 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 or more of these components may notice a change.
For a list of permitted customisations please refer to this document.
Please raise a support ticket if you have any questions relating to the removal of a particular component.
The list of components below are scheduled for deletion in Release 2026.4 of Mercury, currently scheduled for approximately October 2026.

How to identify dependencies on any Legacy X DNU Components in your environment
To identify whether your Mercury environment has dependencies on a particular X DNU component, please follow the steps below:
1. Head to your solution
2. Find the X DNU components
3. Select the component you want to check and select Advanced > Show Dependencies
4. Review all components listed in any of the 3 tabs. If no results are shown, then there is no further action for you to take on this component.
As seen in the example above, this X DNU component is being used by the Contact Form. Therefore, in this example your usual development process should be followed to edit the Contact Form to remove references to the legacy Mercury component.
