Thank you for using IDERA DB Change Manager! Its compare, synchronization, data masking, and auditing capabilities let you track and report on changes, roll out new releases, and pinpoint performance problems resulting from changes to the data, schema, and database configurations. By comparing a live database to a schema or configuration “snapshot” administrators can quickly identify changes and correct problems. By monitoring configuration settings, DBAs can ensure compliance with regulatory policies and performance standards, and maintain overall database performance and availability.

Supported Database Platforms

* For these databases, DB Change Manager supports a subset of this database version’s features/functions.
· DB Change Manager 18.0 should be installed in a different directory than 4.x, 5.x, 6.0.x, 6.1, 6.2, 6.3.x, 2016 (6.3.3), 2016+ (16.5), 16.6, 17.0, and 17.1 versions. If DB Change Manager is installed in the same directory, the following error will result at application start up: "Unable to read workbench state. Workbench UI layout will be reset."
· If one of the conflicting versions is already installed on your machine, either change the default Workspace or delete all files from the Workspace directory. The Workspace directory location appears whenever you start DB Change Manager and can be redefined from this dialog box. If the same Workspace is indicated for the new version, as was indicated previously, the following error will result: "Cannot restore workbench layout."
· If DB Change Manager is already running, you can also modify the Workspace directory by choosing File > Switch Workspace > Other from the Main menu.
· The format in which schema comparisons are saved has changed in 6.x. Use the import feature to import pre-6.0 schema comparison jobs.
Beginning with version 17.0, DB Change Manager provides an upgrade
process for moving jobs and other information from an existing DB Change
Manager 4.0, 5.0, 5.1.x, 5.5.x or 5.6 installation. No upgrade process is
required to move from 6.x installations to DB Change Manager 18.0.
NOTE: You do not have to upgrade to 5.6, and then to DB Change Manager 18.0. The import procedure is the same.
Upgrading from Version 5.0, 5.1.x, 5.5.x or 5.6 to DB Change Manager 2016 (6.3.3), 2016+ (16.5), 16.6, 17.0, 17.1
All objects can be imported from version 5.0, 5.1.x, 5.5.x or 5.6 to DB Change Manager 2016 (6.3.3), 2016+ (16.5), 16.6, 17.0, or 17.1.
