To populate Upgrade Studio with imported files and install updates, all Trex units must have been connected to the PC running Upgrade Studio.
You can import updates/files into Upgrade Studio from a DVD, PC, network, or other physical media. These files include new/updated device descriptions, applications, firmware, operating systems, Trex synchronization files, and updates to Upgrade Studio.
The import option is useful if Upgrade Studio does not have an internet connection and you want to update the Trex unit at your site. You can also import newer versions/updates to Upgrade Studio.
The updates for the Trex unit, except for the Trex synchronization file, must have the .cmspkg file extension. The .cmspkg file extension is the standard format for receiving files to import into Upgrade Studio.
