Change the domain name of Avamar and Data domain.

We are changing the domain name of our organization. Lets say for examle, the old domain name is abc.com and the new domain name would be abc.local.

We are using avamar and data domain to take backup of our environment.

Our environment includes:

1- Avamar (avamar.abc.com) and data domain (dd.abc.com) to take backups of physical and VMs. Both of them have fully qualified domain names that are going to be changed to the new domain, i-e. avamar.abc.local and dd.abc.local.

2- Linux servers that are not part of the domain and have the avamar client installed on them.
3- VMware environment; we are using avamar to backup the VM's using proxies. For each vCenter, we have 2 proxies configured. vCenters, ESXi hosts and proxies, all have fully qualified domain names. We will be creating new vCenters with the new domain name and then add the existing environment to the new vCenters. Old vCenters will be decommissioned later.

Can some one please guide me how to reconfigure avamar to adjust to this domain name change:

1- Change of avamar and data domain domain name, (from avamar.abc.com and dd.abc.local to vamar.abc.local and dd.abc.local).

2- How to configure Avamar and data domain to take backups of the VMs with the changed domain names. 

Any help would be highly appreciated.

Thanks
