Try something like this:-

public static sobject cloneFields(sobject input, sobject output){
    map <String, Schema.SObjectField> fieldMap = schema.getGlobalDescribe().get(input.getsobjecttype().getDescribe().getname().tolowercase()).getDescribe().fields.getMap();
    map <String, Schema.SObjectField> outputfieldMap = schema.getGlobalDescribe().get(output.getsobjecttype().getDescribe().getname().tolowercase()).getDescribe().fields.getMap();
    for (string field : fieldMap.keySet()) {
        Schema.DescribeFieldResult fieldDescribe = fieldmap.get(field).getDescribe();
        if (fieldDescribe.isUpdateable() && fieldDescribe.isAutoNumber() == false && fieldDescribe.isCalculated() == false && fieldDescribe.isCustom()) {
            if (outputfieldmap.containsKey(field)) output.put(field,input.get(field));
        }
    }
    return output;
}
