If we upgrade and have issues can we go backwards to previous version?
Is there a specific version/SP of the core/client that is required to use the new CSA?
What new functionality/fixes are in this new version and is there any documentation on these new features/functionality?
Will there be any changes on the client side (e.g., will we have to run brokerconfig, etc...)
The new features of the CSA are:
64 bit OS
Ability to enable FIPS
You would not be able to revert back to the old version of 4.2. We are looking for people using 9.5, 9.0 SP4, and 9.5 SP1. There will not be any changes on the client side. http://www.landesk.com/uploadedFiles/Solutions/SUMS/LSI-1221_What'sNewin%209.5%20SP1_Final.pdf has information about FIPS 140-2. The updated documentation regarding the new version of the 4.3 is still being updated and has not been released.
