3.6.4 Upgrading to version 1.1 from version 1.0 or older

If you already have an older version of Harvest installed, and want to upgrade, you cannot unpack the new distribution on top of the old one. For example, the change from Version 1.0 to Version 1.1 included some reorganization of the executables, and hence simply installing Version 1.1 on top of Version 1.0 would cause you to use old executables in some cases.

On the other hand, you may not want to start over from scratch with a new software version, as that would not take advantage of the data you have already gathered and indexed. Instead, to upgrade from Harvest Version 1.0 to 1.1, do the following:

  1. Move your old installation to a temporary location.

  2. Install the new Harvest distribution as directed by the release notes.

  3. Then, for each Gatherer or Broker that you were running under the old installation, migrate the server into the new installation.

    you need to move the Gatherer's directory into $HARVEST_HOME/gatherers. Section 4.3 describes the new Gatherer workload specifications which were introduced in Version 1.1; you may modify your Gatherer's configuration file to employ this new functionality.

    you need to move the Broker's directory into $HARVEST_HOME/brokers. You may want, however, to rebuild your broker by using CreateBroker so that you can use the updated query.html and related files.
