Checking Incompatibilities between Version 11.1 and 11.2

As a system administrator, you need to check incompatibilities between consecutive versions before upgrading your system.

The table below lists new features that might lead to compatibility issues or should be taken care of when upgrading - it does not list all new features of this AE version.
New features are described in full in the CA Automic Workload Automation 12.2 Release Highlights.

The columns display the following information:

Topic - Name of the general topic or new feature
Changed behavior - What has been changed
Possible incompatibilities - Impact the change may have
Actions/Countermeasures - What can be done to identify and/or remove possible incompatibilities

Topic	Changed Behavior	Possible incompatibilities	Actions/Countermeasures
General DB change Note: Information and the checking instructions apply to all versions, between your existing installation and the latest you want to upgrade to, respectively.	The DB scheme/structure has been changed.	Custom SQL queries on AE DB do not work anymore.	Check chngdb.sql for general changes Check and adapt relevant SQL/SQLI/SQLJOBS objects accordingly Check and adapt relevant DB queries used in external tools/programs
Release Packaging	The Release Packaging (zip files, folder structure and its content) have been changed. The following files and folders have been removed: Folder ./11/ (the content, e.g. UserInterface, AutomationEngine) are now directly in the base directory and no longer in the sub folder. The uc4setup files and the CD image files have been removed. There is a new installer available for single box installation in the product bundles.	Possibly automated installation routines using release images will not work.	If there are scripts relying on the old package structure, you have to adapt the paths.
CP/WP routing	FORMS request routing toRapid Automation agents has been changed.	When you edit Rapid Automation connection objects, a corresponding Rapid Automation agent has to be active in the same client to retrieve data.	Assign a Rapid Automation agent for relevant clients.
Third party monitoring via External Monitoring Interface	The new state-of-the-art JMX interface EMI (External Monitoring Interface) has been introduced. The existing SNMP interface is still available, but the third party integration with BMC Patrol, HP OpenView, and Tivoli has been de-supported.	There is no incompatibility, but the integration with BMC Patrol, HP OpenView, and Tivoli is not available anymore.	Integrate third party monitoring systems via the new EMI instead.
Doubled MQ tables	MQ tables have been doubled and renamed.	MQ tables might not be considered when you use DB Reorg and existing scripts might fail due to changed table names.	Adapt DB Reorg scripts.
Proxy INI file extensions	Parameters and the format of some parameter values have been changed in the INI file due to functionality improvements.	You will not be able to reuse INI files of Proxy versions prior to v2 without adaptions.	Adapt INI file parameters according to the Proxy user documentation.
