There is no place in the Symantec Management Console to rename an OS image.
Deployment Solution 8.x
It can be accomplished using the following procedure:
1) Open the image in the image explorer. That could be Ghostexp or imgexp. The explorers are found under 'ghost' or 'rdeploy' typically at:
7.1 - C:\Program Files\Altiris\Altiris Agent\Agents\Deployment\Task Handler.
7.5 & newer - "C:\Program Files\Altiris\Deployment\Imaging\ghost\x86\GhostExp86.exe"
-or- "C:\Program Files\Altiris\Deployment\Imaging\ghost\x64\GhostExp64.exe"
2) Save the image under the new name. This wil be a temporary version of the OS file.
3) Use the Resource Import Tool to import the new version of the image. Note: Typically, images for deployment are prepared using Sysprep.
"C:\Program Files\Altiris\Deployment\Tools\ResourceImportTool.exe"
4) Delete the original image and the temporary version. The ResourceImportTool makes a separate copy of the image file.
The original image location can be found by looking at the image package location in console under 'All Settings > Settings > Deployment > Disk Images'
5) Remove the resource for the older version of the image. This is located in the console under 'Manage > Resource'.
From the dropdown locate 'Software Component' and then select 'Image Resource'.
Find the listing for the old version of the OS image. Click OK and delete.
