Preparing devices for data migration

Before you run any software tools to transfer information, you need to make sure that both the old and the new Redmi 9 are ready to go.The first thing to check the battery level: energy-intensive data cloning processes require stable power, so it is better to connect gadgets to chargers or make sure that the battery is more than half full.

The second critical step is to connect to the same Wi-Fi network. While some methods allow you to create a local access point, having a stable router greatly speeds up the transfer of large amounts of data, such as video archives or application libraries. Make sure that both smartphones are enabled wireless modules, and the date and time settings are set to automatic mode to avoid conflicts during synchronization.

⚠️ Note: If you plan to migrate data from iPhone to Android, the process will be different and require the use of a special cable or Mi Mover app in iOS mode.

It’s also worth freeing up space on a new device if it’s not new, although Redmi 9 usually comes with empty memory.Remove unnecessary system updates or temporary files if they occupy a critical volume, although in a standard situation the system itself will warn about the space shortage. Check that the screen is unlocked on the old phone and file transfer is allowed through the phone. USB, If you are planning to use a cable connection.

Using the Mi Mover app for full cloning

The most effective and native way to transfer information to Xiaomi devices is to use the pre-installed utility Mi Mover. This tool was developed by the company's engineers specifically for migration from any Android smartphones, as well as iOS, and allows you to transfer contacts, messages, call log, photos, music, videos, documents and even installed applications along with their data.

To get started, find the app on the new Redmi 9 in the Tools folder or through settings search. When you first start, the system will ask you to accept the user agreement. After that, you will need to select the device role: click "I'm a recipient." On the old phone, also launch Mi Mover (you can download it from the Play Market if there is no built-in one) and select "I'm a sender."

Then the devices need to find each other. The new phone will create a Wi-Fi hotspot that you need to connect to from the old device. The list of available networks will show your Redmi 9 name with the version of the system. Once you connect and confirm the security code, the data selection menu will open, and you can sort the information by category so that you don't drag digital debris to the new device.

• 📱 Contacts and messages: all phone book records, history are transferred SMS and MMS, blacklist.
• 📷 Multimedia: photos, videos, audio recordings of the recorder and music files.
• 📲 Applications: A list of installed programs that will be automatically downloaded from the store on the new device.
• ⚙️ System settings: Wi-Fi passwords, alarm clocks, notes and desktop configuration.

After selecting categories, click the "Send" button and wait for the process to be completed. The speed of copying depends on the amount of data and the quality of the wireless connection. During transfer, do not switch to other applications or block smartphone screens, as this may interrupt the session.

Synchronization through Google account

An alternative and highly reliable method is to use Google Drive cloud storage and system sync, which is ideal if your old phone is broken, lost or simply unavailable for direct connection, but you have backed up beforehand. When you first set up Redmi 9, the system will suggest you recover data from the cloud if you enter the same login and password.

To work, the old device needs to make sure that sync is enabled. Go to Settings → Accounts → Google and check if the ticks are against contacts, calendar, Keep notes and other important sections. It is also advisable to manually back up the Google Photos app to save media files and Google Document Drive.

💡

Use the Traffic Saving mode in Google Photos if you have limited cloud space, but remember that the photo quality will be compressed to 15 MP.

Manual file transfer via USB and computer

For users who are used to controlling every byte of information, or if necessary, transfer gigabytes of video files, the best option is to use a personal computer. This method does not depend on the speed of the Wi-Fi router and allows you to organize the file structure on the new Redmi 9 as convenient as you want. USB-cable and computer with Windows or macOS operating system.

Connect your old smartphone to your PC and select File Transfer (MTP) mode in the notification on your phone screen. Open My Computer, find the device, and copy the desired folders (usually DCIM, Pictures, Download, Music) to your hard drive. Then turn off the old phone, connect Redmi 9, and drag the files to the appropriate internal memory directories.

Special attention should be paid to the DCIM/Camera folder where your photos are stored, and the WhatsApp/Media folder if you use this messenger. When you manually copy, it is important to keep the folder structure, otherwise some applications, such as music players or galleries, may not see new files or sort them incorrectly. After copying, it is recommended to reboot your smartphone so that the system media scanner indexes new data.

• 💾 Reliability: Direct cable connection eliminates the risk of air communication interruption.
• ⚡ Speed: USB 3.0 provides significantly faster recording speeds than Wi-Fi.
• 🗂️ Organization: You can immediately sort files by removing duplicates at the copying stage on the PC.

⚠️ Note: When copying large amounts of data (more than 50 GB) USB, Use only original cables, and cheap charging cables may not be able to withstand long-term current and interrupt transmission, causing files to be damaged.

Transfer of messages and call history

The most sensitive part of migration is often the SMS-Messages and call logs, as standard Android tools are not always willing to share this information between different brands without third-party software. If Mi Mover for some reason did not cope with this task, a proven application will come to the rescue. SMS Backup & Restore: It allows you to create a complete archive of correspondence in the format XML and restore it to a new device.

The process is this: install the app on both phones. On the old device, back up by choosing to save on Google Drive or locally. Then transfer this file to Redmi 9 (via Bluetooth or the cloud) and start recovery. The app will request permission to access SMS and become a default messaging app for the duration of the procedure - this is a normal security requirement of the Android system.

The challenge story is similar, with many users underestimating the importance of keeping a call log until they need to find a number they called six months ago. MIUI You have learned to transfer the call log directly, but only if both devices have the current version of the shell installed. Otherwise, use the import / export function in the Contacts app, selecting the option to save all data on the device. SIM-card or file.vcf, although this method may not save the time and duration of calls.

💡

For guaranteed SMS transfer and call history between different Android brands, it is best to use specialized backup apps, not just system tools.

Problem Solving and Optimization Advice

Even if you follow all the instructions, users may encounter difficulties. For example, the new Redmi 9 may not see the old phone in the Mi Mover device list. In this case, try temporarily disabling Smart Wi-Fi or power saving features on both devices, as they can block local connection. Also helps reboot Wi-Fi module: turn on and off Air Mode.

Another common problem is space shortage. While Redmi 9 has enough storage, if you move data from a 128GB phone to a 32GB model, the system will give you an error, and then you have to selectively migrate, leaving heavy video files on your computer or in the cloud, and remember that the operating system and applications occupy a significant part of the built-in storage.

After a successful data transfer, it is recommended to go to the settings of each important application (banks, social networks, messengers) and log in again. For security reasons, Android does not postpone authorization sessions, requiring re-entering passwords. This can take time, but is a necessary measure to protect your personal data from unauthorized access.

• 🔋 Battery: After transferring data, let the phone lie on a charger 1-2 One hour – active indexing of files.
• 📶 Network: Reconnect to Wi-Fi if passwords are not automatically synced.
• 🧹 Clean: Delete application installation files (.apk) if they have been copied to the download folder.
