There are a few incompatabilities between Harvest version 1.1
and version 1.2.
The Gatherer has improved incremental gatherering support which is
incompatible with version 1.1. To update your existing Gatherer, change
into the Gatherer's Data-Directory (usually the data
subdirectory), and run the following command:
% set path = ($HARVEST_HOME/lib/gatherer $path)
% cd data
% rm -f INDEX.gdbm
This should create the INDEX.gdbm and MD5.gdbm files in
the current directory.
The Broker has a new log format for the admin/LOG file which is
incompatible with version 1.1.
The Cache also has a new log format which is incompatible with version 1.1.
