SG115 migration to xg home

Dear all,

I am desperate ... I have a sg115 hardware appliance with formerly UTM running (home license). Today I wiped the ssd and installed the Sophos XG software iso with success. 


My initial plan was to migrate my utmost home license - that did not work. So I generated a new xg home license key but I am not able to enter it in the licensing dialog. the appliance always want to generate its own number and now set me to basic firewall functions for a month. 


is there any possibility to use the sg115 with xg as home user?


Thanks and best regards
