AXFR request when ixfr-from-differences is set

We have a scenario, where it slaves zones from a upstream master  
capable of IXFR , but it also masters zones maintained by hand, for  
which ixfr-from-differences is set to support IXFR to its downstream  
clients.

Is there a way to take IXFR from a upstream master and support IXFR  
transfer to its downstream clients for both the slaved zones and the  
zones mastered locally ?


Regards,


Vicky Shrestha
