BIRCH - Updating an existing installation

The update process involves deleting a subset of the existing BIRCH directories and downloading and reconfiguring new ones.  All other directories are retained, particularly $BIRCH/local. Since $BIRCH/local contains all local settings and locally-installed software, when the new version of BIRCH is installed, it will be configured according to existing settings.
  1. Uninstall existing BIRCH directories, except $BIRCH/local
  2. Download BIRCH framework and binary files
  3. Run birchconfig
  4. Test your installation

If you are upgrading from BIRCH A1.97 or earlier, replace step 1 above with the the procedure listed here.
