Thanks to everyone in the discussion a few days ago about the Managed content 
and lowlevel storage, I found people's comments really helpful.  Of course this 
just brings more questions that again I ask to this list - regarding the long 
term viability of current fedora usage.

For example, say we deploy a fedora 3.6.2 today and ingest a few TBs of Managed 
content using the fedora legacy low level store, but in a year from now wish to 
migrate to an akubra/iRODS back end.  Does fedora have functionality to 
facilitate a migration such as this?  How would you go about transferring the 
/fedora/data/ from one filesystem to another while maintaining the consistency 
of the fedora database and its foxml?  Would the answer to this question differ 
for Managed or External datastreams? Or could you have one instance of fedora 
that accesses both a legacy store and new store at the same time?  And for 
fedora itself, when version 4 rolls out, what level of effort will there be in 
upgrading fedora 3.x to it?

Thanks,
Eric

Part of the impetus of the Akubra development was to support many different 
kinds of disposition for content across persistence services. I can't speak to 
the efforts around particular vendor-specific solutions, but as a homegrown 
example I can point at:

http://uvalib.github.com/twostore/

which is what we are currently using here at UVa. It may provide some ideas 
about how to use Akubra to create some flexibility and scalability in your 
persistence.
