Changing an operating system is always stressful for the user, especially when it comes to the safety of personal data. Millions of people use Viber for everyday communication, and losing your chat history can be a real disaster. Fortunately, modern technologies make it possible to solve this problem, although the process has its own nuances that differ from simply copying files.
Unlike instant messengers with cloud synchronization by default, the architecture Viber on different platforms initially assumed local storage of backup copies. This means that direct “one-button” transfer within the application itself is often unavailable without the use of specialized software or manual manipulation of backups. However, by following a clear algorithm of actions, you can successfully migrate your dialogs.
Before starting the procedure, it is critical to understand the difference in the file systems Android and iOS. If on a “green robot” the database is stored in an open folder, which can be accessed through a file manager, then in the ecosystem Apple access to the file system is closed to the user. It is this barrier that creates the main difficulty during transfer, requiring the use of a computer as an intermediate link.
Preparing devices and creating a backup copy
The first step is to thoroughly prepare the source device. Make sure that the latest version of the application is installed on your smartphone running Android Viber. Outdated versions may not generate the backup archive correctly, which will lead to errors when restoring on a new platform. Check the availability of free space in the internal memory, since the database with media files can occupy several gigabytes.
Next you need to manually create a backup. Go to the messenger settings and select Account → Viber backup. Click the button Start backup copy. Wait for the process to complete. Please note that a standard backup Google Drive in this case will not help us, since iOS does not know how to read backups from the Google cloud directly for restoration in the application.
⚠️ Attention: Do not delete the Viber application from your Android device until you are 100% sure that the correspondence is successfully displayed on the new iPhone. Deleting the application will permanently erase the local database.
After creating a copy, find the backup file in the phone's memory. Usually it is located along the path /ViberBackups/ in the root of the internal storage or in the folder Android/media/com.viber.voip. The file will have the extension .vbk or .zip. Copy this file to your computer or send it to your email to have access to it when connecting a new device.
☑️ Ready for migration
Using third-party software to convert the database
Since database formats Android and iPhone are not directly compatible, simply copying the file to your Apple device is not enough. You will need specialized software that can read an Android backup, extract messages and media from it, and then “pack” them into an understandable format iOS. There are several solutions on the market, such as iCareFone for Viber, MobileTrans or Backuptrans.
The process of working with such apps is usually standardized. After installing the utility on your computer (Windows or macOS), you need to connect both smartphones with cables to the PC. The app will detect devices and offer a function Transfer Viber between Devices. The algorithm will automatically create a temporary backup from Android, convert it and upload it to the iPhone.
- 🔌 Connect both phones to the computer with original USB cables.
- 💻 Launch the migration app and select the “Android to iOS” mode.
- 📲 Allow USB debugging on Android and trust the computer on your iPhone.
- 🔄 Wait for the conversion and data transfer process to complete.
It is important to note that most quality transfer tools are paid. Free versions often have limitations, such as only allowing you to transfer the last 10 messages or not supporting transferring attachments. If your correspondence is critical, it makes sense to purchase a license for one session.
Before purchasing paid software, check for a trial version (Trial). It will allow you to see whether the app sees your devices and correctly determines the number of messages before you pay for the full version.
Official method through the Move to iOS application
Apple has developed its own solution for user migration - the utility Move to iOS. This method is the most secure from a privacy point of view, as it does not require installing third-party software on your computer. However, it has a strict limitation: it can only be used when setting up a new iPhone for the first time, when the device is in a factory reset state.
If you have already set up your iPhone and are using it, you will have to perform a factory reset through the menu Settings → General → Transfer or reset iPhone → Erase content and settings. After re-activation, at the Wi-Fi setup stage, the system will offer to transfer data from Android. Select the item Transfer data from Android and follow the instructions on the screen.
During the setup process, a code will appear on the iPhone screen. Enter it in the application Move to iOS on your Android smartphone. After connecting the devices, select the type of data to transfer. Make sure the checkbox next to the item Viber is active. The system will automatically transfer the application and message history, converting them to the required format.
| Parameter | Third-party software | Move to iOS | Manual backup |
|---|---|---|---|
| Need to reset iPhone | No | Yes (required) | No |
| Saving media files | Full | Partial | Depends on the method |
| Cost | Paid | Free | Free |
| Difficulty | Low | Medium | High |
What to do if Move to iOS freezes?
Often the process is interrupted due to an unstable Wi-Fi connection between devices. Try turning off mobile data on Android and make sure that both devices are connected to the same 2.4 GHz network and not 5 GHz, as this increases the stability of the connection when transferring large amounts of data.
Recovering data from the iCloud cloud
Once the data is physically moved to the Apple device, the final step is to link the history to your account via the cloud iCloud. This is necessary so that in the future you can easily restore correspondence if you lose your phone or reinstall the application without using a computer.
Open Viber on your iPhone and log into your account using the same phone number as on Android. The application will detect the presence of a local database (which we transferred earlier) and offer to restore it. Agree with this action. After the restoration is complete, go to Settings → Account → Viber backup.
Activate the switch iCloud Backup. Make sure that in the settings of the iPhone itself (in the Apple ID → iCloudsection) there is enough space allocated for the Viber application. If the storage is full, create a new backup manually by clicking the appropriate button. Your history is now protected in the Apple ecosystem.
⚠️ Attention: For iCloud backup to work, Apple ID two-factor authentication must be enabled on your device. Without this function, the option to create a backup in the Viber menu may be inactive.
Solving migration problems
The migration process rarely goes perfectly smoothly for all users. One of the most common problems is mismatch between application versions. If there was a beta version or a very old build on Android, and the current version from the App Store was installed on the iPhone, a conflict in database formats may occur. In this case, try updating or, conversely, finding an APK file of a version close to the one on the iPhone to create a backup.
Another common error is related to lack of space. When transferring via a computer or utility Move to iOS the required free space is 2-3 times larger than the size of the backup copy itself. This is necessary for temporary files and unpacking archives. Clear the memory of both devices before starting the operation.
- 📉 “Not enough space” error: free up at least 5-10 GB on both devices.
- 🔒 Access problem: on Android 11 and higher, access to the Android folder is limited, use Explorer with root access or connect the phone as a drive.
- 📶 Lost connection: when using the Wi-Fi method, disable all VPNs and antiviruses that can block local traffic.
If messages have been transferred, but Pictures or videos are not displayed, check your privacy settings. On your iPhone, go to Settings → Viber and make sure that access to Photo i Media Libraryis allowed. Without this permission, the application will not be able to load visual content from the transferred database.
Frequently asked questions (FAQ)
Can I transfer correspondence if I have already been using an iPhone for several months?
Yes, this is possible, but not through the official Move to iOS application, since it only works during the initial setup. You will have to use third-party computer software that can Inject a database into an already running system, or perform a full reset of the iPhone to factory settings and configure it again via Move to iOS.
Will my stickers and settings be saved after the transfer?
Message history and media files are transferred completely. However, application settings (calls, notifications, themes) are most often reset to default values on the new platform due to differences in OS architecture. Stickers purchased for money are linked to your account and will appear automatically; download free packages again.
Do I need to remove Viber from Android before installing it on iPhone?
No, it’s not necessary. You can use Viber on both devices for a while, but remember that when you activate your account on a new phone, the session on the old device may be terminated for security reasons. It is best to make a transfer, check the operation on the iPhone, and only then delete the application from the old phone.
What to do if the app writes “The backup copy is damaged”?
This may mean that the backup file was created incorrectly or is encrypted with a password that the app cannot guess. Try creating a new backup on Android, disabling the password encryption option (if there is one), and repeat the transfer procedure. Also make sure that the file was not damaged when copied to your computer.
Will Viber call history be transferred?
Unfortunately, the history of incoming and outgoing calls via Viber is not always transferred. Most tools focus on text messages and media files. The call log often depends on the phone's system logs, which are not subject to direct migration between different operating systems.
Successful Viber migration depends on three factors: the relevance of application versions, availability of free space and choosing the right migration tool for your situation (new phone or already used one).
