Prerequisites: Source handset must run Google’s mobile OS 5.0 or later; target device should run iOS 15.5 or later. Install the official Apple migration utility (Google Play) on the source unit and update the messaging application to the latest release on both devices. Disable screen lock on the source unit and grant storage, contacts and microphone/camera permissions when requested. Keep both units plugged in and on the same Wi‑Fi network; close other heavy network apps before starting.

Performance and capacity recommendations: Plan for approximately 6–8 minutes per GB of combined message and media data on a typical home Wi‑Fi; libraries larger than 50 GB can take several hours. Allocate free storage on the target device at least equal to the backup size plus 1 GB. Set both screens to never sleep during the process and avoid interrupting power or network; if migration appears stalled, restart both devices and retry the operation.

Fallback and verification: If the official utility fails, export individual conversation threads using the app’s export function (generates a .txt plus attached media), save those files to cloud storage or email, and copy attachments manually to the target device. Exports serve as archives only – they cannot be re-imported as native conversations into the messaging app. After completion, compare message counts and sample media files on the target device before erasing data on the source handset.

Pre-Transfer Checklist

Back up message history to cloud and to a local file; confirm backup timestamp, total size and that media files are included.

• App and OS versions: update the messaging application and both device operating systems to the latest stable releases available; verify app version in Settings → Help or About.
• Power: charge both devices to at least 50% and keep them connected to a charger during the procedure.
• Network: connect both devices to the same stable Wi‑Fi network (5 GHz recommended); disable VPN and any firewall apps that block local connections.
• Storage: ensure free storage on the target device is at least the backup size plus 500 MB; check backup size inside the app’s Backup or Storage settings.
• Phone number and verification: have the phone number active and able to receive SMS or calls; insert SIM or prepare eSIM on the target device so verification codes can be received.
• Two-step verification: know the PIN or passphrase used for two-step protection; if you cannot recall it, disable two-step verification in the app settings before proceeding.
• Encrypted backups: if backups are encrypted, make sure the encryption passphrase is available; some migration tools cannot read encrypted cloud backups without that passphrase.
• Cables and adapters: prepare a compatible cable (USB‑C to Lightning, USB‑A to Lightning or OTG adapter) if a wired migration is required; test cable connection and data mode beforehand.
• Root / jailbreak: remove root access or un-jailbreak the devices if possible; custom firmware often blocks official migration utilities.
• Large media files: identify video files larger than 100 MB and copy them separately to a computer or cloud storage to avoid timeouts during the main procedure.
• Cloud accounts: sign in to the same cloud accounts used for backups (Google account, Apple ID) and verify that cloud backup and sync are enabled for contacts and photos.
• Contacts and SIM data: export contacts to a vCard or sync to a cloud account so contact entries appear on the target device after setup.
• Notifications and auto-download: temporarily disable automatic media download and low-data restrictions to speed up the process and reduce interruptions.
• Final check: record current app storage usage and number of messages (Settings → Storage) so you can confirm all content arrived correctly after the procedure.

Confirm WhatsApp and OS version requirements

Update both devices to the latest available operating-system release and install the current store release of the messaging app on each device before proceeding.

Minimum software levels: source device OS – Lollipop (5.0) or newer; target device OS – iOS 15. If you beloved this article and also you would like to collect more info regarding 1xbet ios please visit our web-page. 5 or newer; messaging app – the version listed as current in the app store on the source device.

Check OS version: source device – Settings → About phone → Software information (verify the build/version number); target device – Settings → General → About → Software Version.

Check app version: open the messaging app → Settings → Help → App info (the About screen shows the version); alternatively, open the Play Store or App Store listing and compare the installed version to the latest published version.

Apple migration app requirement: install Apple’s official migration application (search the device store for the Apple developer listing), open it on the source device and confirm the pairing/code screen is visible.

Account and verification: the phone number active on the old device must be accessible during account verification on the target device; prepare that number for SMS or call verification.

Factory-state requirement: the target device must be new out of the box or reset to factory settings before attempting migration; do not complete initial messaging-app setup on the target device until migration finishes.

If any item is below the stated minimum, update the OS via Settings → System → Software update (or Settings → General → Software Update on iOS) and update the app via the device’s app store, then re-check version numbers.
