The required platform for OpenACS 4.6 is the same as 4.5, with the exception of OpenFTS. OpenACS 4.6 and later require OpenFTS 0.3.2 for full text search on PostgreSQL. If you have OpenFTS 0.2, you'll need to upgrade.
If upgrading from 4.4, you need to manually run acs-kernel/sql/postgres/upgrade-4.4-4.5.sql. See Bug #632
Make a Backup. Back up the database and filesystem (see the section called “Manual backup and recovery”).
OPTIONAL: Upgrade OpenFTS. the section called “Upgrading OpenFTS from 0.2 to 0.3.2”
Stop the server
svc -d /service/$OPENACS_SERVICE_NAME
Upgrade the filesystem. the section called “Upgrading the OpenACS files”
Start the server
svc -u /service/$OPENACS_SERVICE_NAME
Browse to the package manager,
Select the packages you want to install. This should be everything that says

On the next screen, click
When prompted, restart the server:
Wait a minute, then browse to the package manager,
Check that the kernel upgrade worked by clicking
Alland making sure that
acs-kernelversion is 5.9.0.
Rollback. If anything goes wrong, roll back to the backup snapshot.
