# Migrating from iOS App Center to iOS Unlisted or ABM App

> **Applicable to End Users**

This topic explains how you can migrate from the App Center version of WhatsApp Phone Capture to the unlisted or Apple Business Manager (ABM) version.

> **Important**
> 
> Chat history is lost when transitioning to the new deployment methods.

#### Before You Migrate

On the App Center version of the app:

- Terminate all active communications and keep the app open in the foreground for at least one hour. This ensures that all unarchived communications, including calls, are archived before migration.
- Ensure that the date and time settings on your device is set to Automatic.
  1. Tap **Settings > General > Date & Time.**
  2. Select **Set Automatically**.
- Enable the WakeUp feature:
  1. Tap **Settings** > **Help.**
  2. Enable the **Wake Up when app is closed** option. ![](https://cdn.document360.io/20248637-fef6-4111-82b6-c3bf43c0155e/Images/Documentation/migrating-from-ios-app-center-to-ios-unlisted-or-abm-app-image-t5yrw16p.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A26%3A32Z&se=2026-11-10T17%3A26%3A32Z&sr=c&sp=r&sig=VgsX3iwH0zM7AfOSPIPy9dXbrevhLtZ3LayJJNYsric%3D)
- Disable two-step verification:
  1. Tap **Settings > Account > Two-step verification**
  2. If the two-step verification was enabled, tap **Turn off**.
  3. In the confirmation screen, tap **Turn off**. ![](https://cdn.document360.io/20248637-fef6-4111-82b6-c3bf43c0155e/Images/Documentation/migrating-from-ios-app-center-to-ios-unlisted-or-abm-app-image-nwsbopvb.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A26%3A32Z&se=2026-11-10T17%3A26%3A32Z&sr=c&sp=r&sig=VgsX3iwH0zM7AfOSPIPy9dXbrevhLtZ3LayJJNYsric%3D)
- Do not log out.
- Do not uninstall the app.

#### Migration Steps

Based on your organization's compliance policies, your archive administrator will share the WhatsApp Phone Capture app from ABM or the unlisted app.

1. Install the WhatsApp Phone Capture app shared by your archive administrator. You will see two versions of the same app on your device. ![](https://cdn.document360.io/20248637-fef6-4111-82b6-c3bf43c0155e/Images/Documentation/migrating-from-ios-app-center-to-ios-unlisted-or-abm-app-image-p3kypeto.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A26%3A32Z&se=2026-11-10T17%3A26%3A32Z&sr=c&sp=r&sig=VgsX3iwH0zM7AfOSPIPy9dXbrevhLtZ3LayJJNYsric%3D)
2. Ensure that the app language is set to English.
  1. Tap **Device Settings > Apps > TM WPA > Language**.
  2. Select **English**. ![](https://cdn.document360.io/20248637-fef6-4111-82b6-c3bf43c0155e/Images/Documentation/migrating-from-ios-app-center-to-ios-unlisted-or-abm-app-image-d8fhxf0h.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A26%3A32Z&se=2026-11-10T17%3A26%3A32Z&sr=c&sp=r&sig=VgsX3iwH0zM7AfOSPIPy9dXbrevhLtZ3LayJJNYsric%3D)
