Upgrade Advertising Sales Management from Winter '26 to Spring '26

Advertising Sales Management upgrades automatically from Winter '26 to Spring '26, requiring no manual steps. The system preserves your existing data and configuration settings, and the upgrade causes no service interruption.

Important

If you’re unable to delete a media plan line item in the upgraded org, check if the Apexclasscheck Omni interaction configuration equals True. If it is, update the integration procedure configuration to resolve the issue. For more information, see Update Integration Procedure to Enable the Delete Operations.

• Update Integration Procedure Configuration to Enable Line Item Deletions
  If your Omni interaction configuration apexclass equals True in your org, you can't delete line items in media plans. Update the vplAds-DeleteLineItem integration procedure configuration to resolve this issue.
• Fully Qualified Namespace Requirement for Package Classes
  Apply fully qualified namespaces to both built-in and custom Integration Procedures and Data Mappers to ensure uninterrupted remote action calls in Omnistudio Standard Runtime. Including the required namespace prevents class-not-found errors during remote action calls in Omnistudio. Use fully qualified names for all invoked package classes to ensure uninterrupted updates for line items and other built-in components.
