4. Check if your new installation starts without any issues and once it starts, please stop the OpUtils service and proceed with the restoration process as stated below.
   - Copy the backup files to the new server.
   - Open command prompt as an administrator and navigate to **\OpUtils\bin\backup** directory.
   - Restore the backup file using `RestoreDB.bat` followed by the path of the backup file on the new server.  
     Example:
     ```
     \OpUtils\bin\backup>RestoreDB.bat
     "D:\backupBackUp_APR25_2010_01_17_21_8051.zip"
     ```
   - Once the restoration is complete, restart the OpUtils service on the new server.
5. Copy the files `AdventNetLicense.xml`, `petinfo.dat`, and `product.dat` from the **OpUtils/Lib** folder (for Version 12 and above) of your old server and paste them under the same location on the new server. Restart OpUtils and your license will be updated.

## Linux to Windows server migration steps

To migrate OpUtils from a Linux installation to a Windows installation, follow the steps given below.

1. In the current installation of OpUtils (Linux installation), click on the image icon on the top right corner of your OpUtils web client. Make a note of your existing installation's **Build number** that is given below the **About tab**.

3. In your older installation (Linux installation), take a backup by running the `BackupDB.sh` file under **\OpUtils\bin\backup** folder. Once the backup is complete, a backup file with the current date and time will be created under the **\OpUtils\backup** folder.
4. In the Windows installation, create a folder called **backup** under **\OpUtils** folder and paste the backup file from the Linux installation.
5. Run the `RestoreDB.bat` file under **\OpUtils\bin\backup** folder on the Windows installation by providing the path of the backup file.

   ```
   \OpUtils\bin\backup>RestoreDB.bat
   "D:\backupBackUp_APR25_2010_01_17_21_8051.zip"
