There is a need to ugrade Symantec Messaging Gateway (SMG) without internet access.


SMG can be upgraded locally since version 10 via following way:

1) ISO image of the appliance has to be placed on local web server (http)
2) on SMG please login via SSH as admin
3) then type in: 

mail> update localinstall <URL-to-ISO-file>

where URL-to-ISO-file should be path to the local web server where the image was previously uploaded, e.g.

Here is what is going to happen:
1.After fetching the iso image and individual packages will be checked for a valid signature and invalid signatures will cause upgrade to abort with an error
2.Valid packages will be copied to a temporary location and then temporary files will be used as the repository, and update script will be executed
3.After the update, the temporary package repository and the downloaded ISO image will be removed from the appliance file system.
