Procedure for level upgrade
The procedure for the Level Upgrade is same as that of the Version Upgrade.
Read Version upgrade to perform the update installation. When doing so, replace the term 'Version Upgrade' where it appears with 'Level Upgrade.'
(1) System Environment Settings
For Forced Strong Key mode (STRONGKEYMODE) in the System Environment Settings, the setting before the upgrade is carried over to the updated environment. When you perform the update installation from the version lower than Ver.8.4.0, it is set to "0" (Disabled).
For details about when and how to configure Forced Strong Key mode, refer to Preparation before using Forced Strong Key mode.
