Importing configuration between 2 routers.

I have RB750G in production and want to replace it with a RB450G.
Is it possible to import the configuration from one to the other.
If so how is it done? I was thinking of uploading the config
backups to the new router and hitting restore button in winbox !

This is covered in the manual.

Description
The configuration backup can be used for backing up MikroTik RouterOS configuration to a binary file, which can be stored on the router or downloaded from it using FTP for future use. The configuration restore can be used for restoring the router’s configuration, exactly as it was at the backup creation moment, from a backup file. > The restoration procedure assumes the cofiguration is restored on the same router, where the backup file was originally created, so it will create partially broken configuration if the hardware has been changed.

The configuration export can be used for dumping out complete or partial MikroTik RouterOS configuration to the console screen or to a text (script) file, which can be downloaded from the router using FTP protocol. The configuration dumped is actually a batch of commands that add (without removing the existing configuration) the selected configuration to a router. The configuration import facility executes a batch of console commands from a script file.

Use a system export, edit the resulting file as appropriate (remove references to MAC addresses that will be present, account for the other hardware differences such as interfaces or switch chip sets present, then copy/paste the resulting text file into the 450G via a console connection, or MAC telnet, or a Terminal window in MAC winbox, or get an IP on it and upload the exported script with a .rsc extension and run the import command to execute the commands contained in it.

Hey. Thank you for the prompt response. It didn’t hit me it was covered in the manual.
I need to get some sleep and work on it when fresh.
