Installation and Upgrade Information Upgrading to Blackboard Learn 9.1 SP3

Release Notes for Release 9.1 Service Pack 3 (9.1.30151.0) Page 26

Load-Balanced Systems Warning

The Updater must be run on each Application server and the Collaboration server on a load-

balanced system. After running the Updater the first time, choose the Update an App Server for

all other Application servers and the Collaboration server. This option will upgrade the application

files without making any of the database changes.

Language Pack Changes Warning

To ensure consistency across releases, the Blackboard Learn Updater will compare the existing

en_US language pack against the version that is being installed. The differences are noted and

output in a file called bundle_diff.txt. This file is added to the

blackboard/backups/<updater_time_stamp> directory. Use this file to review the text

differences between releases and make upgrades to any custom Language Packs.
