NetApp Fas3140 and DNS

[ALESSANDRO2225]

Hi all,

i have a NetApp FAS3140, and i am quite new of this environment.

I am in charge of upgrading my only Domain Controller and DNS from Windows 2003 R2 to Windows 2012 R2.

The DC is an additional DC in a 2003 R2 AD Domain.

My first step is to install a second DC/DNS, then change pointments of NetApp to this DNS.

Second step is to install a second DC/DNS and pointng again NetApp to this.

Questions:

1) where is to be done the setting for changing the DNS in NetAPP?

I am aware of \\%name of the controller%\%sharename%\resolv.conf file to be edited by hand: any other setting to be done?

2) May i change DNS in NEtApp without restarting controllers?

3) Any impact changing DNS on NetApp?

Thanks in advance to all
