To upgrade an installation means to reinstall features or components to higher version or build numbers without uninstalling the older ones. All current settings are kept and the database is not overwritten.
You can perform an upgrade using one of the following alternatives:
Run the setup program and it will inform you that a previous version has been detected and an upgrade will be done.
Within the DSM Explorer the preregistered software delivery packages can be used to distribute the components. Software delivery functionality will automatically run an upgrade if an older version exists on the target computer.
Within the DSM Explorer, the Infrastructure Deployment wizard can be used to distribute and install packages to the target computers. For target computers where a previous version is already installed, it is necessary to require an upgrade from within the Deployment: Agent Configuration wizard page. In the input field, Additional Windows install options, the following settings must be entered to request an upgrade on the target computer:
REINSTALL=ALL REINSTALLMODE=vomus
When using the MSI packages directly, you must add the following parameters to the command line:
REINSTALL=ALL, REINSTALLMODE=vomus
Example
msiexec.exe /i"N:\DSM_12_0_1234_1_DVD\WindowsProductFiles_x86\AgentSD\agtsd.msi"
REINSTALL=ALL REINSTALLMODE=vomus /l*v "%temp%\ITRMupdateSDagent.log"
