# Build 3.58.2 (04tRl000001EpLRIA0) ## Duplicate Settings - Migration to the new JSON based format From this version, the Duplicate Settings have been moved from SObejcts into a unique JSON. This reduces the complexity of Duplicate settings spanned over many objects (mainly DDQ Duplicate Objects, DDQ Duplicate fields...). This change requires a migration step that is made simpler by using a dedicated migration package provided by Delpha. * After the main Delpha package is installed, add the **DelphaUpgrade258** package (unmanaged) to your org. It will facilitate the migration process. * Package Id: 04tRl000001EAVBIA4 * Package URL : **/packaging/installPackage.apexp?p0=**04tRl000001EAVBIA4 Once the upgrade package is installed, open a developer console and run the script below. ```apex delpha.DDQ_DuplicateSettingsMigration.quickMigration(); ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
