Upgrading from older versions

If you are upgrading from a previous release of GNATS, you probably do not want to delete your current configuration files or your current database. The new GNATS can be installed around the older version.

You need to:

• Specify your current GNATS_ROOT on the command line to configure when you build the new tools, with

  configure --with-full-gnats --with-gnats-root=GNATS_ROOT
  

  (See section Configuring and compiling the software.)
• Remove the directory `gnats-bin' from GNATS_ROOT; it is no longer used.
• Update your current mail aliases to reflect that queue-pr now resides in `exec-prefix/lib/gnats' rather than `GNATS_ROOT/gnats-bin' (see section Where GNATS lives).
• Change the default PATH for the gnats user to search the directories `exec-prefix/bin' and `exec-prefix/lib/gnats'.
• Reinstall the GNATS user tools on all other hosts on your network (see section Installing the user tools).
• Redistribute send-pr to your Submitter Sites (see section Configuring send-pr for the outside world). This is not absolutely necessary, as GNATS can read Problem Reports generated by older versions of send-pr. It should be done eventually, however, as send-pr is improved over older verisons.
