I would like to know if it's possible to make a configuration file for a RUT955. We have al lot of RUT955 with the same configuration. Someone told me that the solution to make an backup from a RUT955 and import that to another is not a good solution because he copies the serial number. Is it possible to make an backup and import it without overwriting the serial number? Or do you have an other solution so it can save me a lot of time configuring all routers?
