Any way to migrate configurations from Sonicwall NSA4600 to Sophos XG?

Hello,

 

I have a customer that wants to move from Sonicwall NSA4600 to Sophos XG 330. The problem here is that there are hundreds of rules and IP/Service opbjects that needs to be transfered somehow.. It would be nice to get at least the object database from NSA to Sophos. Anyone else done migrations like this?
