Upcoming ASC and AAC MAPI deprecation, Migration Options to Advantage+

The streamlined Advantage+ experience drives App, Sales and Leads campaigns to default to the optimal, automation-first setup and allows advertisers and partners simplified access to Meta’s latest and most performant automation products. We are executing a phased deprecation of the legacy APIs and migration to the new Automation Unification, Advantage+ setup for Marketing API developers.

Following the launch of the streamlined Advantage+ experience for sales and app objectives in V23.0 of the Marketing API and the planned deprecation of the Advantage Shopping Campaigns (ASC) and Advantage App Campaign (AAC) APIs for campaign creation in MAPI V25.0 (Q1 2026), we are launching Advantage+ Migrations to support developers in transitioning legacy ASC/AAC campaigns into the new Advantage+ structure.

From V24.0 (8th October), we will no longer allow new ASC/AAC campaigns to be created using the legacy ASC/AAC APIs. Developers may revert to previous MAPI versions (i.e., v23.0 or less) to continue using or editing legacy ASC/AAC APIs, however we highly recommend that developers start creating and using Advantage+ campaigns.

Starting from 8th October, we are also making the following options available for developers:

• Copy and Migrate using the new, optional migrate_to_advantage_plus field
  • Developers may use the existing Copies endpoint to copy their ASC campaign into a new campaign in the Advantage+ structure. This will yield a new campaign ID, and the new campaign will reflect the updated Advantage+ structure.
  • This applies to ASC campaigns only. AAC campaigns can not be copied.
• Migrate only using the new, optional migrate_to_advantage_plus field
  • Developers may initiate a POST call on their existing ASC/AAC campaign with the new migrate_to_advantage_plus field to migrate the campaign into Advantage+ structure. This will maintain the same campaign ID, and the new campaign will reflect the updated Advantage+ structure.
• Manual Ads Manager Migration
  • Partners and advertisers can also choose to use the existing manual Ads Manager migration by editing an existing campaign. For eligible campaigns, making any campaign edit such as name or budget will trigger a prompt to upgrade to ‘Advantage + Campaign Budget’. Once the change is published it will migrate and will reflect the updated Advantage+ structure.
    • This method is only available where developers have the required access and permissions to advertisers’ Ads Manager accounts.

Note: Not all campaigns are eligible for migration at this stage, exclusions include;

• Campaigns using existing_customer_budget_percentage can only be migrated to Advantage+ structure by duplicating the campaign in the Ads Manager. You may open the campaign in Ads Manager for instructions on how to duplicate into the Advantage+ structure. For recreating as a new campaign, please see “Replicate Existing Customer Budget Percentage”.
• ASC Campaigns that contain more than 50 ads in the ad set. These will still be editable after v25.0 of the Marketing API launches, but will be unable to be duplicated.

Please review the updated developer docs and FAQs to see all details of this change.
