protocol. Concurrently with the file transfer, the target file server responds to client
read/write requests for access to the file system.
Claim 1 is illustrative of the invention and reads as follows:
1. A method of migrating a file system from a source file server to a target file
server in a data network while permitting clients to have concurrent
read/write access to the file system, said method comprising:
the target file server issuing directory read requests and file read requests
to the source file server in accordance with a network file access protocol to
transfer the file system from the source file server to the target file server, and
concurrent with the transfer of the file system from the source file server to
the target file server, the target file server responding to client read/write requests
for access to the file system.
The Examiner relies on the following prior art:
Marsland 5,923,878 Jul. 13, 1999
Beeler, Jr. (Beeler) 5,974,563 Oct. 26, 1999
Rao 6,078,929 Jun. 20, 2000
Claims 1, 3, 24, 26-28, 45, and 47-49 stand rejected under 35 U.S.C. § 102(e) as
being anticipated by Beeler. In rejections under 35 U.S.C. § 103(a), the Examiner
rejects claim 2 as being unpatentable over Beeler in view of Rao, and rejects claims 4,
5, 25, and 46 as being unpatentable over Beeler in view of Marsland.
Rather than reiterate the arguments of Appellants and the Examiner, reference is
made to the Briefs1 and Answer for the respective details.
