WhatsApp automatically takes a backup of its chats on the local storage every day. Therefore, you can just copy the local backup file and move it to your new Android device. While setting up your WhatsApp account, you can just restore the existing backup. Though, this method will only work if you are using the same phone number on both the devices.

You can also maintain a copy of your WhatsApp backup on Google Drive as well. WhatsApp also lets us enable the automatic backup feature and select its frequency as daily, weekly, or monthly. So you have a second copy of your WhatsApp data and the chat history won’t be lost. Check here steps to learn how to transfer WhatsApp data via Google Drive backup.

WhatsApp has a solution to back all messages up so you can carry them to your new phone. Given how popular the messaging app is and that it’s used by almost all people, it’s important to know how to transfer your old chats to your new device.

WhatsApp chats have not only important contacts and information at times, but also media attachments that might be important for you to carry over to your new device. The easiest way to transfer chats is to back them up on Google Cloud or iCloud and then restore them on your new phone.

WhatsApp transfer backup & restore:

There are basically three ways by which we can transfer our whatsapp data to new phone.

1) Transfer WhatsApp chats the easy way with the cloud

2) Transfer WhatsApp chats manually with a PC

3) Transferring WhatsApp chats from iPhone to Android

1. Google Drive backup and restore

Newer versions of WhatsApp include automatic Google Drive backups, which makes the process of transferring your WhatsApp chat history between phones even easier than before.

• You simply tap the trio of dots at the top left of the screen and go to Settings > Chats > Chat backup. 
• From here, you can back up manually, or set it to automatically backup as regularly as you like. When WhatsApp is reinstalled, it will prompt you to recover your chats and multimedia from Google Drive.
• Chats and contacts will appear in the app instantly, whilst media will begin downloading in the background.
• This is the method we use when we switch smartphones for reviews and testing etc.

2. Manually backing up chats and restoring them

If you’ve yet to receive the Google Drive WhatsApp update, or just like to do things the old-school way, it’s still reasonably easy to create a backup and move it to your new phone. Simply proceed as follows:

• Open the Settings menu of WhatsApp, tap on Chats and calls and then tap Chat backup.
• If your old Android phone and new one both primarily use an external SD card for memory, simply back up to the SD card and then switch it out of your old phone, and put it into your new one. Restore from the SD card to a newly installed WhatsApp on your new phone.
• For phones that save to internal memory, such as most newer devices, connect your smartphone to your PC via USB cable, and navigate to the internal memory of the device to the folder WhatsApp / Database. This is where all the backup files are saved with a date. Copy the file with the latest creation date (it will have a different name from the automatic backups created) onto your PC in an easy to find location (such as your desktop).
• Install WhatsApp on your new device but do not start the app!
• Connect your new device to the PC via USB. Because you’ve already downloaded WhatsApp onto your new handset, the folder WhatsApp / Databases should now exist. If not, you can manually create a new Databases folder in the WhatsApp folder.
• Copy your WhatsApp conversation backup file into this folder.
• Now start WhatsApp on your new phone and verify your phone number. You should now get a notification that a message backup was found. Just tap Restore, and you’re done. After a few seconds, all of your messages should have appeared on your new device.

3. Transferring WhatsApp chats from iPhone to Android

Please note that without using a questionable third-party tool, it is not currently possible to transfer chats from iOS to Android or vice versa. iPhone users can, however, use iCloud to get their old

messages on their new iPhone in much the same way as Android users can make use of the Google Drive backup feature.

For iPhones the process of backing up chats on WhatsApp is just as easy.

– Go to your Apple ID and turn on iCloud if you do not have it on.

– Now open WhatsApp and go to Settings.

– Click on ‘Chats’ and then click on ‘Chat Backup’. Here too you can pick between manually backing it up or automatically letting it happen weekly or monthly. You also get an option to include or exclude videos in this case.

Now when you get WhatsApp on your new device, you will be prompted to restore old chats from the iCloud.

Important note – If you are moving from iOS to Android or vice versa, you will not be able to restore your old chats on the new device since iOS won’t restore it from Google Drive and Android doesn’t have access to the iCloud.
