you would use a CD/DVD with the updates and use it as the source for update.
Look at aptitude configuration for sources one of which can be a CD/DVD.

Are you looking to upgrade the setup or update certain packages or a combination of the two?
Presumably you have an identical reference system with access to the internet on which you tested your applications to make sure they will continue to work following the update/upgrade.

I personally use apt-mirror. Here is the how-to I used to set mine up.  Feel free to change or skip a step if you don't think you'll need it, ie I skipped the crontab section since I want to tell my system when to run.
