Buying a new Redmi 9T smartphone is always a surge of enthusiasm, but often overshadowed by fear of the procedure of migration of personal information. Users are rightly afraid of losing important contacts, correspondence history or photos taken over the years in the process of changing the device. Fortunately, Xiaomi’s ecosystem is designed to minimize risks and simplify this process to a few touches of the screen.
There are several proven methods to transfer data from Xiaomi to Xiaomi Redmi 9T, each with its own features and advantages. The choice of the specific method depends on the amount of information, Internet connection speed and personal preferences of the owner of the gadget. In this article, we will discuss all the current options in detail, paying special attention to the standard tools of the system.
To start with, modern versions of the MIUI shell have powerful built-in migration functionality, and you don't have to be an IT expert to complete this operation successfully, because the interface is as simple as possible for the mass user, the main thing is to follow the steps carefully and not interrupt the file transfer process.
Using the Mi Mover application: a standard solution
The most efficient and quickest way is to use the built-in Mi Mover app, a tool designed by Xiaomi engineers to migrate data between the brand’s devices, providing not only multimedia but also system settings. You don’t need to download third-party software to get started, as the utility is already pre-installed in the Tools folder on both smartphones.
The process starts with running the app on both devices, and on the old phone you have to select the status "I send" and on the new Redmi. 9T —"I'm the recipient. Then the recipient's screen will appear. QR-The code that should be scanned by the camera of the old device, the connection is over a direct Wi-Fi channel, which provides high speed transfer without the use of mobile traffic.
Importantly, Mi Mover allows you to selectively approach copying, so you can tick only the right categories, like contacts, messages and apps, leaving garbage in the old place, which is especially convenient if the internal memory of the old phone is much larger than the new one.

⚠️ Warning: Do not leave the Mi Mover app or lock your smartphone screens until the process is complete, otherwise the connection may break and the procedure will have to start again.
Once the scan is complete, the system will suggest selecting data to transfer. The new Redmi 9T will create a temporary Wi-Fi hotspot that will connect the old phone, transfer speeds can reach 20-40 MB/s, which is much faster than Bluetooth.
Sync with Google Account and Cloud
An alternative and often more reliable method is to use Google cloud services, ideal for those who plan to replace devices regularly or want to have a backup of data in remote storage. Before starting the procedure on an old phone, you need to make sure that the sync is on and off.
To activate the process, go to the settings menu and find the Accounts and Sync section, where you should check that the sliders opposite contacts, calendar and notes are active, and click the Sync button to force the data to be updated on the server, which ensures that the latest information will be available on the new device.

The main advantage of this method is independence from the physical condition of the old phone, and even if the previous device crashed or lost, you can recover key data by simply logging into your account on a new gadget.
Manual copying through a computer
For users who prefer complete control of the process or do not have a stable Wi-Fi connection, the classic method of copying via a PC is suitable. USB-It's a cable and a computer, but it allows you to visually control the folder structure and transfer files of any format. USB"File transfer" (MTP).

Transfer of messages and call logs
Migration deserves special attention. SMS-Messages and call history, as this data is often not synced with Google by default in full.The built-in Mi Mover app does this best, saving even the most. MMS However, if you use third-party launchers or specific applications for calling, additional actions may be required.
In some cases, users are faced with a situation where messages are moved but not displayed in the standard application.This is solved by clearing the Messages app cache in the new phone settings. Go to Settings → Apps → All Apps → Messages and select Clear Cache.

☑️ Checklist before transfer
Transfer of applications and their data
The modern Android operating system allows you to transfer not only yourself APK-App files, but also their data. When using Mi Mover or recovering from Google Account, on the screen of the new Redmi 9T You'll see a list of apps that you can install, and you'll download the latest versions from the Play Market.
However, data within apps (game progress, social media login) are not always portable; banking apps will require device re-entry and linking for security reasons; games using Google Play Games or Mi Account will restore progress automatically after logging in to the profile.
Applications that do not have cloud sync may need to use the “Backup” function in settings. MIUI. This tool creates a complete image of installed programs that can be saved on the SD-map or cloud to Mi Cloud and then deploy to a new device.

Comparison of data transfer methods
To make it easier for you to choose the best way, we have prepared a comparison table that will help you weigh the pros and cons of each method depending on your situation and technical capabilities.
| Method | Speed. | What's transferable | Difficulty |
|---|---|---|---|
| Mi Mover | Tall. | Everything (photos, contacts, apps, settings) | Low. |
| Google Account | Medium | Contacts, photos, applications (without data) | Low. |
| Computer (USB) | Depends on the cable. | Files only (photos, videos, documents) | Medium |
| Bluetooth | Very low. | Separate files | Tall. |
As the table shows, Mi Mover is the undisputed leader in functionality and speed for the Xiaomi-Xiaomi pair.Using a computer is only justified if there is no Wi-Fi network or if you need to transfer terabytes of data when wireless transmission would take too long.
Bluetooth is almost not used for mass migration in 2026, because of the extremely low transfer rate, which is a fraction of a megabyte per second, which is reserved for the emergency transmission of one contact or photo.
Possible problems and solutions
Data migration can cause technical disruptions, and users often complain that transmissions are stuck at a certain percentage, most of which are due to an unstable Wi-Fi signal or energy saving that kills the background transmission process.
It is recommended to turn off the power saving mode on both devices and bring the phones closer to each other during the transfer, and if the process is interrupted, it is better to delete temporary files and start again, as the resumption often works incorrectly.
Another common problem is the lack of memory on the Redmi 9T. Before starting the procedure, make sure that there is more free space on the new device than the amount of data planned for transfer.
⚠️ Note: If contacts are displayed twice after transfer, use the “Combine Duplicates” function in the Contacts app or delete unnecessary entries through the Google Contacts web interface.
In rare cases, you may need to reset your network settings on a new device if you don’t transfer passwords from Wi-Fi hotspots. This is solved through the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
