Question : netapp change active directory domain

Can someone recommend procedure of reconfiguring netapp filer for a new active directory domain.
we are using re branded net app (IBM3700) .
it is setup as a member of xxx.yyyyy.com domain and we are planning to migrate it to yyyyy.com domain.
DNS servers for both domains are different,  and i'm sure we would have to change them in the filer config as well.

Step by step instruction would be appreciated.

Answer : netapp change active directory domain

than you will need to follow the rebook document, that should give you a lot of insight.  If you run into any gotcha's just let me know.  Make sure your Netapp and your new Domain controllers are within 5 min. on time, otherwise the filer will not be able to register with AD
