Have you read the SAP note 799639 - IDES - General Information about the usage of IDES systems?
Here is what the note says:
>>
Support Packages / Upgrade / EHPs
IDES specific Support Packages do not exist.
Patching and Upgrade of IDES systems are no longer supported. IDES should only be operated as a seperate installation. Each new release requires a new installation!
Due to the complexity of the IDES systems and the number of preinstalled components/AddOns it is not possible any more to generate a consistant maintenance (MOPZ) within the Solution Manager. Because of this technical restriction we recommend to wait for coming IDES versions/releases.
Kernel Updates / Kernel Patches are recommended!
