- If in my network I have more SEPM, the JDB file must be saved on all SEPM servers?
---> if there are replicating then SEPMs can replicate packages and definitions, if not , then yes you need to have JDB on all the SEPMs
2.Is possible to update the LUA server to the rapid release definition and use LUA policy to distribuite the rapid release?
LUA cannot be updated manually (offline) as of now however it can update from another LUAadmin( which has internet access)
In your infrastructure if you have SCCM or Tivoli you can utilize the third party content distribution option in SEPM
or use the Intelligent updater ( .exe) file and push it via SCCM or Altiris
