One of my major reasons to want to move from 7.2 to 7.4 is that I
suffer from incredible index bloat. Reindex on one of my tables takes
about 45 minutes per each of the 3 indexes on it during which time
part of my system is blocked.
Granted, the one-time cost of the migration to 7.4 will probably take
about 5 hours of dump/restore, but at least with the re-indexing I can
do one 45 minute block at a atime stretched over a few days early
in the morning.
I think some sort of scripted migration/upgrade tool that used
eRServer would be way cool.
