When you get a new device, the Code42 app's replace device wizard can help you transfer files, move your backup, and update settings from a previous device. We recommend using the replace device wizard if you are:
- Moving a backup to a new device
- Replacing an old device
- Replacing your device's main hard drive
- Recovering after an operating system reinstall
Code42 for Enterprise:
- These instructions apply to users working at endpoint devices with Code42 app version 5.1 and later. They do not include transferring Windows user settings (USMT data).
- To work with older versions of the Code42 app, the Code42 console, or USMT data, select the appropriate article from Use Code42 to simplify device migration.

Code42 for Enterprise
- Backup starts once you complete the replace device wizard. In the meantime, your device is not backing up.
- Any changes you make to Device Preferences prior to completing the wizard will be replaced with your previous device's preferences in Step 3 of the replace device wizard.
- If your account uses an enhanced security setting (archive key password or custom key), you must enter your security information several times when replacing a device. You are prompted to enter your archive key password or custom key:
- After signing in to a device that has never backed up
- Before viewing and transferring files from your backup to your new device
- After settings are transferred to your new device
- You must perform the steps below directly on the new device while signed in as the user who owns the device. If you attempt to use remote desktop (RDP) or another similar tool to perform the steps remotely, the Code42 app is not able to determine the correct username. This causes the replace device wizard to fail and prevents files from being properly restored.
It's OK if you can't complete all of the replace device steps during a single session. You can close the Code42 app, or shut down your device, at any time. After choosing the device you want to replace, the Code42 app automatically remembers where you left off and returns you to that step. Additionally, any files you choose to transfer will continue to transfer even when the Code42 app is closed.
New device setup recommendations
When replacing a device, before undertaking the following steps, we recommend setting up the new device with the same username and drive letter that you used on your previous device. If the username or drive letter on your new device is different than on your old device, you may need to update your file selection to include the new location of your files, and you risk having backup problems.
If you take the time before device replacement to set up the new device with the same username and drive letter, the Code42 app can then run a file verification scan to synchronize with the destination and continue backing up files using the same username and drive letter on the new device.
Before you begin
Install the Code42 app on the new device. The first time you sign in to the Code42 app on a device, the Code42 app detects whether there are other devices on your account. If there are other devices on your account, the Code42 app asks you to either:
- Add New Device: Starts a new backup for this device. Use this option if you plan to use both devices.
- Replace Existing: Starts the replace device wizard, which includes choosing a device, transferring files, and updating settings. Use this option if you plan to use the new device instead of the existing device.
Choose Replace Existing to use the replace device wizard. Click Start to begin the wizard.
Throughout the replace device wizard, you can mouse over underlined text for additional explanations and helpful tips.
Step 1: Choose a device to replace
After starting the replace device wizard, all of the devices on your account display, sorted by most recent activity.
- Choose the device you want to replace. You can identify which device to replace by:
- Device name: By default, the device name matches the user name of your device.
- Date Created On: Date the Code42 app was installed on that device.
- Click Continue.
In the following, less common, situations, the Code42 app may ask you for additional input based on the device selected.
- Different operating system: If your current device has a different operating system than the device selected, the Code42 app will notify you about limitations. Learn more about these limitations before continuing.
- No cloud destination: If the device you selected backed up exclusively to local destinations, then the Code42 app will prompt you to attach a local destination now.
Step 2: Transfer files to your new device
You can now transfer files from your previous device to this device. Because users may have different goals and needs when replacing a device, there isn't a single "right way" to transfer files. The steps below describe the most common need, which is transferring your entire user folder.
We strongly recommend transferring all of the files from your previous backup to this device. Any files in your backup that aren't transferred are retained as deleted files. Deleted files are at greater risk for unintentional data loss because they are less visible in your backup file selection, and they may be periodically removed from your backup based on your retention settings. If you or your administrator already transferred files to your device, you can click Skip File Transfer to skip this step.
- On the Step 2 screen, click Select Files to open the file browser.
- (Optional) If your previous device backed up to multiple destinations, select the destination to use from Restore files from.
For Code42 federal cloud destinations, the backup set list appears if your previous device had multiple backup sets that use the same destination. Select the backup set that contains the files to restore.
- Browse to the user folder for your previous device (typically, the folder matching your name) and select a single folder within your user folder (for example, Documents).
Files transfer in the order that they are added to the downloads manager. Consequently, we recommend choosing the folder you think you will need access to first.
- Do the following:
- Code42 app version 6.8.3 and later:
- Click Restore Files.
- (Applies only if you have multiple devices) From the menu, select the device that originally backed up the files you want to restore.
- Code42 app version 6.8.2 and earlier:
- Click Get Files.
- Code42 app version 6.8.3 and later:
- From Save selected files to, select Other.
- From the file browser for your device, select the user folder on your new device (typically, your name).
- Click Go to begin transferring the selected folder.
The transfer is added to your downloads manager.
- Repeat Steps 2–5 for each additional folder in your user folder (Desktop, Downloads, Pictures, Music, and so on).
- When you have queued every folder in your user folder for transfer, click Continue.
All of the folders and files queued for transfer display. It's important to let all files transfer before continuing to the next step. This way, when the Code42 app scans your device after transferring your settings, it can accurately compare the files on your device and those in your existing backup archive. The Continue button is disabled whenever files are transferring or queued for transfer.
- Once all of your transfers are complete, click Continue.
- It is safe to close the Code42 app while the files restore in the background.
- If you are restoring a large amount of data, consider optimizing your computer settings to prevent disruptions.
- Alternatively, if you don't want to restore all of the files at once, you can shut down or put your device to sleep and restoration will resume where it left off when it is powered on again.
Step 3: Transfer settings to new device
Next, the wizard will transfer and update your settings, which includes:
- Linking your previous device's backup archives to this device.
- Transferring your file selection, backup settings, and device preferences to this device.
- Updating your file selection to include the new device.
Code42 for Enterprise only: The Code42 app will add the folders that your administrator has chosen as your default backup selection.
- Click Continue.
You are signed out of the Code42 app.
- Sign into the Code42 app.
The success message, "Your device is ready!" displays.
- Click Finish.
The Home screen displays.
Your device will now resume backing up.
What to expect after you replace a device
After replacing your device, the Code42 app resumes normal operation. But, you might notice the following behaviors or differences.
File verification scan
You might notice the file verification scan running after replacing your device. By default, the file verification scan runs daily to inspect your file selection for any new, changed, or deleted files. The Code42 app runs additional verification scans to detect data corruption, purge files that are no longer selected for backup, and prune file versions and deleted files according to your frequency and version settings.
During the scan, the Code42 app is calculating the full size of your backup selection. As a result, it cannot report the percent complete. This is expected behavior. However, if you have concerns, you can take some additional steps to confirm that your backup is not starting over.
Manage files warning
For efficiency, we recommend waiting until your backup reaches 100% complete before you deselect any folders or files copied from your previous device to your new backup selection. This lets the Code42 app record that a file has a new location, rather than backing up a new copy of the file. As a result, you avoid repeating the potentially lengthy initial backup.
Be careful of removing folders and files from your new backup selection. Deselecting folders and files immediately deletes them from your backup archive. You cannot restore folders or files once you delete them from your backup selection.

About the replace device wizard
No. You must complete the replace device wizard before your device will start backing up.
It's okay if you can't complete all of the steps during a single session. You can close the Code42 app, or shut down your device, at any time. After choosing the device you want to replace, the Code42 app automatically remembers where you left off and returns you to that step.
Yes. The Code42 app will transfer files, even when it is closed. If you turn off your device, the Code42 app will resume transferring files when you turn your device back on.
Enter and exit the replace device wizard
Yes, you can open the replace device wizard at any time. From the menu bar, select Tools > Replace device (Windows and Linux) or File > Replace device (Mac) to open the replace device wizard.
If your old device is currently backing up, then wait for the backup to complete before replacing it.
If you already started a new backup on the new device, replacing it with a previous device:
- Deletes the backup archive. Step 3 of the replace device wizard transfers settings from the previous device to your current device. This includes replacing the new backup archives with those from the replaced device.
- Overwrites any changes to device preferences and backup settings. The new settings and preferences are overwritten with those from the previous device.
Choose a device to replace
Yes. In Step 1, select Add as new device to exit the replace device wizard. Alternatively, if you already started a backup of your current device, choose Use current device to continue where it left off.
If you accidentally select the wrong device, you can change it at any time up until you transfer the selected device's previous settings to this device. In the upper-left corner of Step 2, select Change Device.
Yes, but the Code42 app will warn you about certain limitations and differences when compared to replacing a device with the same operating system. Learn more about replacing a device with a different operating system.
Transfer files to your new device
Yes. If you or your administrator already transferred files from your previous device to your current device, the replace device wizard can still help you transfer your settings and reconnect your previous backup archives to your current device. By reconnecting to the previous device's backup archives, you avoid repeating the potentially lengthy, initial backup. In Step 2, you can choose Skip file transfer.
Yes. If the device you are replacing was backed up to a local destination, you can add that destination and transfer files.
Yes. In Step 2, use the As of Date filter to choose a date prior to corruption of your files. If you are unsure of the exact date of file corruption, try transferring a single file first. Once you narrow down the date of corruption, proceed with transferring the remaining files.
It's normal for the replace device wizard to take some time, especially when transferring a large amount of data. Whenever possible, we recommend completing all three steps of the replace device wizard. However, if you encounter an unexpected error and become stuck in the replace device wizard, you can manually force it to quit.
