Trend Micro recommends backing up the server’s program files and database, which can be restored if there are problems with the upgrade.
C:\Program Files\Trend Micro\OfficeScan\Addon\TMSM
C:\Program Files\Trend Micro\Apex One\Addon\TMSM
C:\Program Files (x86)\Trend Micro\OfficeScan\Addon\TMSM
C:\Program Files (x86)\Trend Micro\Apex One\Addon\TMSM
Files to back up:
Database files. See Backing Up the Server Database.
The size of the file to be downloaded displays beside the Download button.
Plug-in Manager downloads the package to <server installation folder>\PCCSRV\Download.
<server installation folder> is typically C:\Program Files\Trend Micro\OfficeScan or C:\Program Files\Trend Micro\Apex One.
You can navigate away from the screen during the download.
If you encounter problems downloading the package, check the server update logs on the Apex One or OfficeScan web console. On the main menu, click Logs > Server Update.
