> I have already prepared the IP transition on tiger to make the new IP addresses provide the same services on tiger so that I hope that there is no actual outage of the services other than the rebooting time.
> 
> If you happened to use the IP address on your cronjob or programs, please make sure that you switch it with the new one.
> 
> IMPORTANT
> =========================================
> tiger will need to reboot to kick in a new kernel and mount the NFS space with the new IP addresses at the same time.
> ========================================== 
> 
> Please let me know if you have any questions or concerns about this IP transition.
