Back up the database and filesystem.

Upgrade the filesystem for packages/acs-kernel. the section called “Upgrading the OpenACS files”

Upgrade the kernel manually. (There is a script to do most of the rest: /contrib/misc/upgrade_4.6_to_5.0.sh on HEAD). You'll still have to do a lot of stuff manually, but automated trial and error is much more fun.)

[root root]# su - $OPENACS_SERVICE_NAME
[$OPENACS_SERVICE_NAME aolserver]$ cd /var/lib/aolserver/ $OPENACS_SERVICE_NAME/packages/acs-kernel/sql/postgresql/upgrade

Manually execute each of the upgrade scripts in sequence, either from within psql or from the command line with commands such as psql -f upgrade-4.6.3-4.6.4.sql $OPENACS_SERVICE_NAME. Run the scripts in this order (order is tentative, not verified):

psql -f upgrade-4.6.3-4.6.4.sql $OPENACS_SERVICE_NAME
psql -f upgrade-4.6.4-4.6.5.sql $OPENACS_SERVICE_NAME
psql -f upgrade-4.6.5-4.6.6.sql $OPENACS_SERVICE_NAME
psql -f upgrade-4.7d-4.7.2d.sql $OPENACS_SERVICE_NAME
psql -f upgrade-4.7.2d-5.0d.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0d-5.0d2.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0d2-5.0d3.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0d6-5.0d7.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0d7-5.0d9.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0d11-5.0d12.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0.0a4-5.0.0a5.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0.0b1-5.0.0b2.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0.0b2-5.0.0b3.sql $OPENACS_SERVICE_NAME
psql -f upgrade-5.0.0b3-5.0.0b4.sql $OPENACS_SERVICE_NAME

Upgrade ACS Service Contracts manually:

[$OPENACS_SERVICE_NAME aolserver]$ cd /var/lib/aolserver/ $OPENACS_SERVICE_NAME/packages/acs-service-contracts/sql/postgresql/upgrade
psql -f upgrade-4.7d2-4.7d3.sql $OPENACS_SERVICE_NAME

Load acs-authentication data model.

psql -f /var/lib/aolserver/$OPENACS_SERVICE_NAME/openacs-5/packages/acs-authentication/sql/postgresql/acs-authentication-create.sql $OPENACS_SERVICE_NAME

Load acs-lang data model.

psql -f /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-lang/sql/postgresql/acs-lang-create.sql $OPENACS_SERVICE_NAME

(This step may overlap with the two previous steps, but I think it's harmless?) Create a file which will be executed on startup which takes care of a few issues with authentication and internationalization: create $OPENACS_SERVICE_NAME/tcl/zzz-postload.tcl containing:

if {![apm_package_installed_p acs-lang]} {
apm_package_install -enable -mount_path acs-lang $::acs::rootdir/packages/acs-lang/acs-lang.info
lang::catalog::import -locales [list "en_US"]
}

if {![apm_package_installed_p acs-authentication]} {
apm_package_install -enable $::acs::rootdir/packages/acs-authentication/acs-authentication.info
apm_parameter_register "UsePasswordWidgetForUsername" \
"Should we hide what the user types in the username
field, the way we do with the password field? Set
this to 1 if you are using sensitive information
such as social security number for username." \
acs-kernel 0 number \
security 1 1
parameter::set_value -package_id [ad_acs_kernel_id] -parameter UsePasswordWidgetForUsername -value 0
}

If you can login, visit /acs-admin/apm and upgrade acs-kernel and acs-service-contract and uncheck the data model scripts. Restart. If everything is still working, make another backup of the database.

Upgrade other packages via the APM
