- All newly archived files will expire 270 days from the day they
     are archived. What about the several thousand files that have been
     previously archived? Are they still under the 'No Limit' retention
     or will they now be under the 270 days retention?

Norm,
In response you your question, the first time that schedule runs, those several
thousand files will rebind to the new 270 day retention.  This will take some 
time,
as each file is compared and then changed. Not a big deal really, let ADSM
handle it.
