Regardless of which device you're switching from, whether it's an old Android or even an iPhone, there are proven algorithms for doing things. It's important to understand that backup is a critical step that should not be neglected even when using cloud services. Let's look at where to start preparing for data portability.
Preparing devices for data migration
Before running any transfer programs, you need to perform a number of preparatory steps. First of all, make sure that both smartphones are charged at least 50-60%, as the process can be energy intensive and long-term use of the screen and communication modules quickly consumes charge. It is also recommended to check the availability of free space on the new Redmi Note 9 to make sure that the amount of internal memory is sufficient to accommodate all files from the old device.
Both phones need to be connected to a stable Wi-Fi network if you plan to use cloud methods or transfer large amounts of data over a local network. Although some utilities create their own access point, Internet access may be required to authenticate accounts or download application updates. In addition, Bluetooth and GPS should be enabled on both devices, since they are often used to detect neighboring gadgets.
☑️ Preparation for transfer
If the old phone has screen protection (pattern lock, PIN-In the migration process, the system may request multiple times to verify the identity of the owner in order to access protected memory areas or accounts. It is also worth temporarily disabling power saving on both devices so that the operating system does not interrupt the background file transfer process.
Using the Mi Mover app for Android
The most efficient and quickest way to transfer data between Android smartphones is the Mi Mover app, which is designed specifically for the Xiaomi ecosystem and allows you to transfer contacts, messages, call history, photos, music, videos, documents and even installed applications along with their data.
To get started, open the app on both phones. On the new Redmi Note 9, select Recipient, and on the old device, Sender. QR-The code that will appear on the screen of the new phone, or you can choose the device from the list of available to connect. Once you establish the connection, you will see a detailed menu for selecting data categories.
💡
When transferring large amounts of data (over 20 GB), it is recommended to keep the phones close and not lock the screens to speed up the process and avoid connection breaks.
Special attention should be paid to the System Data section, where you can transfer not only media files, but also settings, including the location of icons on the desktop, alarm clocks and notes. After selecting all the necessary items, click the Send button and the copying process will begin. The transfer speed can vary depending on the number of files and the quality of the antenna modules of both smartphones.

Transferring data through Google Account
An alternative and classic method is to use Google’s cloud service, ideal for those who want to save contacts, calendar, notes and installed app lists without being tied to the smartphone brand. When the new Redmi Note 9 is activated, the system will prompt you to recover data from the last backup associated with your Google account.
To make this work correctly, you need to make sure that the old device is fully synced. Go to Google's settings and check the date of the last copy. The list of stored data usually includes contacts, calendar events, Keep notes, Chrome passwords and a list of applications. Photos and videos are uploaded to Google Photos if the corresponding feature is enabled.
The main advantage of this method is that it is independent of the physical presence of the old phone when you set up a new one. Just enter your login and password, and the phone itself will start pulling information from the cloud. However, it is worth remembering that recovering a large number of applications and their data can take a considerable time and require a stable Internet connection.
It is important to note that data within some applications may not be saved if the developer has not provided synchronization via Google Drive, in such cases it is better to use specific backup functions within the applications themselves or use Mi Mover, which can clone and program content.
Manual file transfer via USB and PC
For users who prefer full control of the process or have very large amounts of media (for example, hundreds of gigabytes of video in 4K), the best option is to use the computer as an intermediate storage, which is also useful if wireless transmission is unstable or too slow.
Connect your old phone to your computer through USB-cable and select the "File Transfer" mode» (MTP) In the notification, copy all the folders you need (DCIM, Pictures, Download, Music) to your PC hard drive. Then disable the old device, plug in the Redmi Note 9 and move the files to the appropriate internal memory directories.
💡
Manual method via PC is the only way to securely transfer files without compression and loss of quality, and bypass the limitations of wireless protocols when working with archives larger than 50 GB.
Also remember to manually copy messenger folders if you want to save your correspondence history that is not synced through the cloud. For example, for Telegram it can be a folder with downloaded files, and for local backups of other applications, the folder structure on the new phone will be created automatically when the corresponding programs are first started.

Nuances of the transfer of messages and messengers
Special attention should be paid to the topic of correspondence in messengers such as WhatsApp, Viber and Telegram. Standard backup methods often do not affect media files inside chats or require separate activation of the functions of saving history. WhatsApp, for example, you need to back up in chat settings by selecting Google Drive or local save.
⚠️ Note: When transferring data from iPhone to Redmi Note 9, WhatsApp’s correspondence history is not automatically transferred via Mi Mover. USB-C) and utilities "Move to iOS" in reverse mode or third-party software on PC.
For Viber and Telegram, the situation is simpler: Telegram stores the entire history on the server, so it is enough to simply log in. Viber requires you to create a local backup before reset or transfer, which you then need to find and activate on the new device when you first start.
If you use banking applications, keep in mind that their data is never automatically transferred for security reasons, you will have to re-authorize, confirm login via SMS or Push tokens, and in some cases re-assign cards, which is normal practice to protect users’ financial assets.
