What issues are involved with naming the new Volume the same as the old?  Or is that an issue?  I work with FCSvr specific set ups.  Never had to expand/replace Volumes, but I know it's coming for a couple of clients.  I'll assume Volume name may not be a problem, once Devices and such are created and pointed to, and mount points are created.  But, should I watch out for anything?

You should be able to deal with Final Cut Server change by modifying the Device configuration in Final Cut Server if you need to, rather than being significantly concerned about the Volume name change if it's just the Volume Name that has changed.

Theory I'm thinking of is; Volume gets "replaced" by larger Volume all together.  Not just "expanded" upon.  Just a theoretical scenario that my be presented to me soon.  I'm all for expanding, rather than replacing, but, it's not a perfect world...

I want to ask you what the best method would be for moving the data.
Should this be done with snfsdefrag?
      
If possible, I like to:
copy data to another known good volume,
add new storage,
recreate the volume,
copy data to the new volume.
    

I agree with Arek, although we have moved data with snfsdefrag between pools
then normalized once old LUNs/Pools have been retired to save from having
downtime.  But that's possibly the most tedious work I've ever had to do...
If you can find a time to bring the SAN down and do it manually I would do
so.  Added benefit of doing that is you truly defragment the volume.
