Symantec NETBACKUP 7 - Manual (Page 43)

For the new host, you must use the same host name. The new host cannot host a
deduplication storage server already.
Reasons to replace the host include a lease swap or perhaps the current
deduplication storage server host does not meet your performance requirements.
Warning: The new host must use the same byte order as the old host. If it does
not, you cannot access the deduplicated data.
In computing, endianness describes the byte order that represents data: big endian
and little endian. For example, Sun SPARC processors and Intel processors use
different byte orders. Therefore, you cannot replace a Solaris SPARC host with a
host that has an Intel processor.

Configure the new host so it
meets deduplication
requirements
See the storage vendor's documentation. Move the storage to the new
host.
See the NetBackup Installation Guide for UNIX and Linux.
See the NetBackup Installation Guide for Windows.
Install the NetBackup media
server software on the new
host
If you have load balancing servers, delete the NetBackup
Deduplication Engine credentials on those media servers.
On each load balancing server, run the following command:
