     <b>Important</b>: If you are performing the migration in multiple stages (e.g. migrating account-by-account to the new server), skip to the next step.</font>
   </span>
   <br/>
   <br/>
   <br/>
  </li>
  <li>
   <font color=black>Copy the configuration files to, or manually re-configure the setting for the new AhsayCBS server.</font>
   <br/>
   <br/>
   <ul>
    <li>
     <font color=black><b>For migration to an <u>exact same version</u> (e.g. AhsayCBS version 8.1.0.50 to version 8.1.0.50), you can copy the configuration files over to the new server</b>:</font>
     <br/>
     <br/>
     <ul>
      <li>
       <font color=black>Shutdown the AhsayCBS service on the new AhsayCBS server.</font>

       %Applicaton Home%\conf\Branding
       <br/>
       <br/>
       Note: Note: AhsayCBS migration procedure is only applicable when the current and new hardware run same OS platform (Windows to Windows, or Linux to Linux); we do not support cross-platform migration (Linux to Windows, AhsayUBS to Linux, etc).
       <br>
       <br>
       Also, if you have not shutdown the existing AhsayCBS server, you may be in violation of licensing terms by running two servers with the same license. Only one license key may be applied to any one active CBS server. From the CBS Web Console, access the License page to verify.
