Heard today we might be adding some ADVA equipment [of some kind] to our network...
Is that the old FSP3000 device, or the current FSP3000R7 platform (Optical Transport - we use this for DWDM)?
If the later, then my research indicates you are out of luck. Configuration is a binary file for which the vendor has declined to provide any decode or translation resources (on multiple requests).
Their newer FSP150 equipment generates plain-text config files than can manipulated in all the usual ways.
