# Transfer using rsync This article discusses transferring data to a new host using `rsync`. This approach uses a generated SSH key for authentication, making it the most reliable and therefore the recommended method. {% embed url="" %} Schematically, the transfer process can be depicted as follows:

## Creating the Script File and Adding Content 1. First, establish an SSH connection to your **new** MikoPBX. You can find instructions on how to do this in [this article](https://docs.mikopbx.com/mikopbx/english/faq/troubleshooting/connecting-to-a-pbx-using-ssh/putty).

Successful SSH connection to the new MikoPBX

2. Once connected, switch to the console (**\[9] Console**). First, you need to create a directory to store the script file. Use the following command: ``` mkdir -p /storage/usbdisk1/transfer ``` 3. Navigate to the created directory: ``` cd /storage/usbdisk1/transfer ``` 4. Create the file "**transfer-rsync.sh**" to store the script: ``` touch transfer-rsync.sh ```

5. Next, you need to fill the file with the script content. You can find the script [here](https://gist.github.com/excla1mmm/c9891306b459cac0c7ea3c785ab0936e). Use the following command to download the script: ```php curl -o /storage/usbdisk1/transfer/transfer-rsync.sh https://gist.githubusercontent.com/excla1mmm/c9891306b459cac0c7ea3c785ab0936e/raw/ec57ab60ee48112b4a16635e7b47955e5a044513/transfer-rsync.sh ``` ## Running and Using the Script 1. Make the file executable: ```php chmod +x transfer-rsync.sh ``` 2. Run the script: ```php ./transfer-rsync.sh ``` 3. You will be prompted to enter necessary information about your old MikoPBX: * IP address of your old station * Username for SSH authentication * Port for SSH authentication

4. Next, you’ll be asked whether to generate a new key. If you haven’t done this before, type "y" to confirm. If you previously generated a key for accessing the second MikoPBX, type "n":

5. A new SSH key will be created. You must copy this key and insert it into the web interface of your old MikoPBX at **General Settings** → **SSH** → **SSH Authorized keys** field.

6. After saving the key on the old MikoPBX, wait a few seconds, then press any key to continue the script. The transfer of all data to the new host will begin. This may take some time. {% hint style="danger" %} After the transfer, always verify the integrity of all data before retiring the old MikoPBX! {% endhint %}
