Migrate Identity Application 4.7.4 portail settings to another server


I need to migrate Identity Application 4.7.4 to another server. 

I have already setup the new server with Identity Application, but need to copy all the portal settings, like "acces, branding, customization".

I don't find any export/import option, is there any way to do it with an easier way than copy it manually ?

Thanks a lot.
