If you set highmigration=0, a bad thing happens when some user tries to do a
mnual backup midday.  The first byte that lands in the pool triggers a
migration.  That ends very quickly, the nthe second byte (OK I exaggerate a
bit) starts a new migration...

The effect is that the TSM server thrashes madly starting and stopping
migrations.
So we suggest highmigration=5 lo=0.
