Actually, no. As Dan pointed out in his message, you would have
to accept a full backup of the data from the smaller of the
two servers. ADSM will not allow you to rename two nodes into
one. If you attempt to rename a node to an existing error, ADSM
complains with the error

 "ANR2147E RENAME NODE: Node XXXXXX is already registered."

If you went the import/export route, you may be able to
do the following:

 1) rename the smaller node to what you will ultimately
    name the single large file server

 2) perform a full export of this newly renamed node

 3) delete this node from ADSM

 4) rename the larger node to what you will ultimately
    name the single large file server

 5) import the export created in step 2

Mind you, if you have like named filespaces on both servers, they
will get automatically renamed--data in the two will *not* be
merged as a part of the import process.
