Important Notes on Upgrading

Changing language of an existing installation on upgrade is not possible. If you specify a different language identifier, for example, in the response file for an unattended upgrade, the upgrade is aborted.
After you upgrade the DSM domain manager, from the DSM Explorer, navigate to Control Panel, Configuration, Configuration Policy, PolicyName, DSM, Manager, Infrastructure Deployment, and ensure that the value of the parameter "Always deploy primer" is set to False.
When the parameter value is set to False, the manager upgrades the DMprimer of only those target computers whose DMprimer version is lower than that of the manager. If you set the parameter to True, the manager upgrades the DMprimer of target computers regardless of the DMprimer version.
Certificates are not updated during the upgrade process; this is to protect any existing custom certificates which may already be in place on the computer. If a master image has been updated to use new custom certificates, they are copied to the ‘bin’ folder during installation, but are not applied to the certificate store.
Custom certificates must be applied during initial installations or applied manually after an upgrade process. The commands necessary to import new certificates are detailed in the Authentication section in the Security Features chapter.
