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

Warning: The new host must use the same byte order as the old host. If it does
not, you cannot access the deduplicated data.
Incomputing, endiannessdescribes thebyte orderthat representsdata: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.
