.NET Framework V4.0
JAMS V5.0 requires V4.0 of the .NET Framework. If it is not already installed, the JAMS setup program will download and install V4.0 of the .NET Framework.
The JAMS Agent works with V2.0 (or higher) of the .NET Framework.
The JAMS V4.9 Admin Client can connect to and administer a JAMS V5.0 server so you can continue to use the JAMS 4.9 Admin Client on machines that cannot be upgraded to V4.0 of the .NET Framework.
Report Definitions
There have been significant improvements to the JAMS Report Designer which requires that report definitions be updated. All of the JAMS predefined reports will be replaced during the upgrade. If you have customized any of the predefined reports without saving them to a new name, you should save your custom reports under a new name or to a file before upgrading to JAMS V5.0.
As a precaution, you should save any custom reports to a file before upgrading to JAMS V5.0. This will protect you in case you encounter an issue opening the report in the V5.0 designer.
After upgrading to V5.0, you must update any custom reports by opening them in the designer and clicking the "Save" button.
Backwards Compatibility
JAMS V5.0 is fully compatible with previous versions of JAMS. However you must make a small change to a configuration on V4.x JAMS servers before you can monitor jobs using the V5.0 JAMS Client. The configuration file that needs to be updated is in the C:\Program Files\MVPSI\JAMS\Scheduler directory and is named JAMSServer.exe.config. Open that file in any text editor, look for this line:
<bindingRedirect oldVersion="4.2.0.0-4.9999.9999.9999"
change the 4.9999.9999.9999 to 5.9999.9999.9999. Save the file then restart the JAMSServer service.
