Let me restate what I think you're asking about:

You have a NAS device; I'll call it "Netapp".

You have some filesystems on it.  I'll call an exemplar /local/vcu

You have a solaris box that has been backing up /local/vcu by mounting
it and adding it to the DOMAIN.

You now want to keep on doing that from a different piece of hardware.

If this is the case, then I think you should be mostly fine;  you may
have some ACL issues because of some random difference between Solaris
and (I assume) Linux NFS, but you can just define a server stanza on New
Hardware that uses the old node name, make sure the paths are the same,
and then soldier on.

If you're using the solaris server nodename to contain the NFS
filespaces, you might need to re-back-up the server itself.

The most common problem we have with such issues is changing aggregation
of filespaces.  i.e. we used to back up home3 and home5 from node
proxy-01, but now we want to do home5 and home8 together on proxy-08.
There, you've got some issues;  the fully deployed solution to that is
to associate each filespace with its own nodename, and then you can move
nodes _and_ filespaces around on proxy hardware to your hearts' content.
