The 100% I was referring to was both the Pct Util and Pct Migr fields.  I
have looked throughout the activity logs and have found issues where
migration had tried to occur, but at that point in time our temp license
key ran out for edt and acsls.  (This is a new environment that we are
testing/configuring and do not have permanent keys available at this
point.)    I received many messages within the activity log of the
following nature:

Ending with an internal server error detected.  I am working through some
messy issues with ACSLS right now.  I was just wondering why it didn't
retry migrations when I finally had ACSLS working?  Or at that point did it
retry so many times and then just give up?  Thanks in advance for any
suggestions/help!

You didn't specify what statistical field your "100%" value came from,
but realize that it is the Pct Migr value which governs migration,
not Pct Util.  I summarize the distinction in ADSM QuickFacts.
Note also that caching keeps copies of files in a storage pool,
though migration has occurred.
