Upgrade instructions

Upgrading from 2.4.0

--------------------

Before beginning, back up your WeBWorK database and course directories.

To update WeBWorK to exactly 2.4.1, use the following commands:

cd /opt/webwork/webwork2
cvs -q up -dP -rrel-2-4-1

To update WeBWorK to the "tip" of the 2.4.x branch, which is mostly stable and
includes bug fixes and new features before they are officially released, use the
following commands:

cd /opt/webwork/webwork2
cvs -q up -dP -rrel-2-4-dev

If you are using the National Problem Library, re-run bin/NPL-update to update
the database format to the latest version.

No database changes occurred between 2.4.0 and 2.4.1, so running bin/wwdb_upgrade
is not necessary. No configuration file changes occurred between 

Upgrading from 2.3.x

--------------------

Before beginning, back up your WeBWorK database and course directories.

To update WeBWorK to exactly 2.4.1, use the following commands:

cd /opt/webwork/webwork2
cvs -q up -dP -rrel-2-4-1

To update WeBWorK to the "tip" of the 2.4.x branch, which is mostly stable and
includes bug fixes and new features before they are officially released, use the
following commands:

cd /opt/webwork/webwork2
cvs -q up -dP -rrel-2-4-dev

Merge changes from global.conf.dist, database.conf.dist, and
webwork.apache-config (if you are using Apache 1) or webwork.apache2-config (if
you are using Apache 2) into your configuration files.

Run bin/wwdb_upgrade -v to upgrade your database. If you receive errors about
modelCourse it is OK to go on -- modelCourse is not a real course.

If you are using the National Problem Library, the loadDB2 script in the
database_problems directory has been replaced with a new bin/NPL-update script
in the main webwork2 distribution. The problem library metadata is now stored
within the main webwork database. Run bin/NPL-update to load the problem
metadata into the its new location. It is safe to remove the separate
ProblemLibrary database.

Upgrading from 2.2.x

--------------------

Make sure you are using the sql_single database layout for all the courses you
wish to continue to use. After you upgrade, courses using other database
layouts will be inaccessible. Move non-sql_single courses out of your courses
directory.

The standard directory layout of WeBWorK has changed since 2.2.x. We now suggest
that you place the webwork2 directory, as well as the pg, courses, and
libraries, directories in /opt/webwork rather than in /opt.

To update WeBWorK to exactly 2.4.1, use the following commands:

cd /opt/webwork/webwork2
cvs -q up -dP -rrel-2-4-1

To update WeBWorK to the "tip" of the 2.4.x branch, which is mostly stable and
includes bug fixes and new features before they are officially released, use the
following commands:

cd /opt/webwork/webwork2
cvs -q up -dP -rrel-2-4-dev

Merge changes from global.conf.dist, database.conf.dist, and
webwork.apache-config into your configuration files.

Run bin/wwdb_check -v to verify that your database is up-to-date for version
2.3.0 (the first version that included automated database upgrades). Then run
bin/wwdb_upgrade -v to upgrade to bring your database up-to-date for version
2.4.1.
