WhatsApp does not store messages and files transferred on its servers, this means that your conversation history is only stored in the memory of your phone and, if you have it configured, in the backups. Therefore, if you change your phone and do not make a transfer of your chats history when you open your WhatsApp session with your number on the new device you can only see the groups in which you were included but all messages will be archived and disappear. To avoid this, you can move your WhatsApp chats to a new phone without losing anything, as well as the specific details depending on whether it is Android or iPhone.
The first step to ensure that you will be able to recover your conversations and files on your new phone is to back up your WhatsApp. You may have your account set up to have automatic backups made on a fairly regular basis, but either way, we recommend that you make a last manual backup before transferring your chats to the new phone so that you don't lose any messages.
To do this, if you have an Android phone, open WhatsApp, click Settings > Settings > Chats > Backup.
If you have an iPhone, open WhatsApp, go to Settings > Chats > Backup.
If you are going to move your WhatsApp chats from an Android phone to another Android, the process will be very simple:
1. First verify that your backup has been successfully completed. It will be stored by default in your Google Drive account.
2. Next, insert your SIM card into your new phone.
3. Synchronize your Google Drive account on the new phone.
4. Install the WhatsApp app</bold>. You can download it here.
5. When you start the app it will ask for your phone number, enter it and you will receive an SMS with a confirmation code.
6. Enter the code and your WhatsApp session will start.
7. At this point you will be asked to confirm the recovery of your backup. Confirm and all your conversations and files will appear as they were on the old phone.
If you are going to make a switch from Android to iPhone or vice versa you will not be able to make a direct recovery of your WhatsApp backup since Android saves by default its backups in Google Drive and iPhone in iCloud.
These two cloud storage services have a different writing system so it is not possible for a WhatsApp backup initially saved in iCloud to be read by Google Drive and vice versa. Therefore, in principle you can not recover your conversations.
However, if you also use Telegram, you can still avoid losing your conversations and files from the chats you had on WhatsApp on your old phone and just export them one by one.
Go to the chat, click on the name of your contact on top, scroll down to the export chat option and once the content is loaded, select the Telegram option and then tap Saved Messages > Send. Here we explain in more detail how to do these exports step by step.
This will allow you to have a compressed file in Telegram with your old WhatsApp conversations and documents. It's not as convenient as the full WhatsApp transfer by backup but it saves you from losing all that information.
