You want to know what to consider when upgrading from older versions of SMS DOM to SMS Domino 7.5.
From the Symantec™ Mail Security for Domino® 2007 Implementation Guide:
If you are upgrading Mail Security supports upgrades from version 4.x and higher only.
If you are running version 2.x or lower, you must uninstall the product and then install version 7.5.
If you are running version 3.x, do one of the following:
Uninstall version 3.x, and then install version 7.5.
Install version 5.x, and then install version 7.5.
Requirements that you must meet before you can upgrade to version 7.5.
For version 4.0: None.
For version 4.1 or 5.0: Ensure that Symantec Premium AntiSpam is disabled before you install version 7.5, if enabled.
When you upgrade from version 4.x or higher, you can upgrade your previous databases.
The databases that you choose to keep during the installation process are upgraded the next time that you start the Lotus Domino server.
