[Building Sakai] [Deploying Sakai] Converting Oracle LONGs to LOBs?

[mizematr at notes.udayton.edu]

I don't think so.  We converted a solitary table long before we converted 
all tables and did not run into trouble.

Is there any downside to converting only a single table 
(MAILARCHIVE_MESSAGE)?   We are seeing ORA-22295 coming from the Email 
Archive in the 2.6 code that we just put into production.   The existing 
XML column is LONG but the newly added BODY column is a CLOB. 

I've created an issue for this ( SAK-16463 ).
