On the importance of running iwfsshrink after iwmigrate

Andy Knipp

Migrated a branch (6.7.2 to 7.1) 10 Editions or so, 5K files in the WA.

iwfsshrink output:

Files examined: 2707760
Bytes examined: 70174798602
Files found to be duplicates: 2654334

(not finished removing yet -only 2000 files removed about 3GB of 70GB total)

So of the 2.71 M files on my system, 2.65 M are dups.
