Reconfigure NBU Appliance 5220

Hi,

We change our enviromint domain name and we need to change the domain name for all servers.

And we have NBU appliance 5220 2.5.2 as media server.

Master server 7.5.0.5 : windows 2008 R2.

We need to chenge the domian name for master and media server.

First, if we change the domin name for master server, did i'll lost the administation consol configuration and settings or it will not changed.

Secound, if we change the domain name for media server, did the images that on appliance will be lost or can be accessible?

And are there any recommended steps to do this task.

Thanks,
