This guide is intended for those upgrading from 3.1.x or
earlier versions to 3.2.x. The best advice is
don't. That is, it is highly recommended that you
install the 3.2 release in a separate directory tree and treat
everything as if you were installing it for the first
time. This is not just because this is a beta release. There
are several main reasons for this:
Text files, such as config files, result templates, etc. are
the same between releases, so you will probably wish to copy
these to your new installation.
- The htmerge program now only merges. You
do not need to run it after running htdig as before. The
"cleanup" duties have been moved to the htpurge program that also deletes
URLs. The sample rundig script is modified accordingly.
- The default directory structure of this release is
different from previous releases, more in line with other UNIX
- The databases are all in different formats. This version
cannot read databases from previous versions since the new
formats have significantly more information and this cannot be
reconstructed from old databases. This goes for fuzzy
databases as well. Future versions can use the new htdump and htload programs to dump and load
databases to/from text files. These will also allow databases
to be transfered between platforms.
Additionally, you may find things a bit rough at first. We
appreciate your comments and suggestions, especially in the
form of performance comparisons with the 3.1.x
releases. Additionally, there are several things planned for
the final 3.2.0 release that have not been implemented yet:
