### Back up the old Synctool version

1. Create a backup folder in Windows File Explorer and name it **Zivver Synctool backup**.

Tip

**Easy to find**

Create the backup folder in your existing Zivver Synctool folder for easy reference in the future.

2. Copy and paste all files in the existing Zivver Synctool folder (e.g. `.exe`; `.exe.config`; `.dll`; `.dll.config`) to your backup folder.
3. Create a subfolder in the folder **Zivver Synctool backup** called **Profile backup** .
4. Copy and paste all Synctool profiles (i.e. `.xml` files) from the directory that stores the Synctool profiles to the **Profile backup** folder.

Tip

**Where can I find the Synctool profiles?**

Open the profile in the Synctool and go to **Profile** \> **Profile Details**. Here you can find the **Profile location**.

_You have now backed up the Zivver Synctool and its profiles._

### Verify the new Synctool works as expected

1. Go to your downloads folder and open the unzipped Synctool folder. Ensure you keep all files that were present in the ZIP in that folder (i.e. `.exe`; `.exe.config`).
2. Run the `Zivver.Synctool.App.exe`.

Tip

**If no profiles are shown, browse to the service account AppData**

You may find Synctool profiles in the AppData of a service account that is used to [run the Synctool on a daily basis via the Windows Task Scheduler](https://docs.zivver.com/en/admin/synctool-v2/automated-synchronisation.html). Go to `C:\Users\"service-account-name"\AppData\Roaming\Zivver\Synctool` to check if there are Synctool profiles stored.

3. Go through the tabs **Profile**, **Target (Zivver)**, **Sources**, and **Syncing** to verify everything works as expected.
4. Go to the tab **Manual Synchronization** and run a manual synchronization.

_You have now verified the new Synctool works as expected._

You can inspect the log files to see if the synchronization was successful at the location you specified under **Logging** \> **Event logging**](https://docs.zivver.com/en/admin/synctool-v2/logs.html). Please [create a support ticket](https://support.zivver.com/s/contactsupport?language=en_US) if you run into any errors that you can not resolve.

### Replace the old Synctool with the new Synctool

When [the new Synctool works as expected](https://docs.zivver.com/en/admin/synctool-v2/update-synctool.html#verify-the-new-synctool-works-as-expected) you can replace the old Synctool version with the new Synctool version from your Downloads folder. This section assumes [the old Synctool version is already backed up](https://docs.zivver.com/en/admin/synctool-v2/update-synctool.html#back-up-the-old-synctool-version).

1. Go to your downloads folder and open the unzipped Synctool folder.
2. Copy all files in the folder (e.g. `.exe`; `config` files).
3. Go to your existing Zivver Synctool folder and delete the old files.
4. Paste the new Synctool in the existing Synctool folder.
5. [Verify the Synctool version is updated](https://docs.zivver.com/en/admin/synctool-v2/update-synctool.html#check-the-synctool-version).

_You have successfully updated the Zivver Synctool._
