Routers often get upgraded or swapped out for a number of reasons. This document provides the user with some basic steps to migrate the configuration from an existing router to a new router.


Prerequisites

Requirements

Before you use the information in this document, make sure that you meet these requirements:
  • Access to a Trivial File Transfer Protocol (TFTP) or File Transfer Protocol (FTP) server.
  • Connectivity - Routers must be able to access the FTP or TFTP server. Use the ping command to verify connectivity.


    Make a Backup of the Configuration

    There are several methods to choose from in order to back up and restore a configuration:
    • Use a TFTP server
    • Use an FTP server
    • Use a Terminal Emulation Program
    • Automatic Backup of Configuration using the Kron Method
    • Backup Configuration to a TFTP Server
       

    Configuration Script :-

    kron policy-list AutoSaveConfig
    cli write
    exit

    kron occurrence AutoSaveConfigSchedule at 23:50 Fri recurring
    policy-list AutoSaveConfig

    kron policy-list Backup
    cli show startup-config | redirect tftp://10.10.10.10/Router-10.10.10.1-Backup.cfg
    exit
