There are a few different ways to transfer WhatsApp data from an Android device to an iPhone:
Use Google Drive to back up and restore your WhatsApp messages:
On your Android device, open WhatsApp and go to "Settings" > "Chats" > "Chat backup".
Tap "Back up to Google Drive" and select the backup frequency and Google account you want to use.
Once the backup is complete, install WhatsApp on your iPhone and set it up using the same phone number that you used on your Android device.
During the setup process, WhatsApp will ask if you want to restore your messages from a backup. Tap "Restore" and select the Google Drive backup that you created on your Android device.
Transfer your WhatsApp data using iTunes:
Connect your Android device to your computer and open iTunes.
Click on the device icon and go to the "Backups" section.
Select "This computer" and click "Back Up Now".
Once the backup is complete, disconnect your Android device and connect your iPhone to your computer.
In iTunes, click on the iPhone icon and go to the "Backups" section.
Select "Restore Backup" and choose the backup that you just created from your Android device.
Use a third-party tool to transfer your WhatsApp data:
There are several third-party tools available that can help you transfer WhatsApp data from an Android device to an iPhone. Some popular options include dr.fone - WhatsApp Transfer and MobileTrans.
