They're command line tools. upgrade_export makes the .tgz file and upgrade_import reads it.
In NGX they're found in $FWDIR/bin/upgrade_tools
If you need to download them, I think you can find them here:
Check Point Software: SmartCenter Tools It's as simple as running it, such as
./upgrade_export /var/fp2export.tgz
The /var partition usually has the most free disk space. You should cut back on the number of database revisions you have or the file can be huge.
The .tgz file is platform-neutral. You can take one created on a Nokia and import it into SPLAT, for instance. Unfortunately FP2 is ancient. I think you would have to upgrade to FP3 and then to R55 and then to NGX.
There is no way to print it out from the file, but the file contains ALL of the information needed to restore your SmartCenter. It's an excellent disaster recovery tool.
Check Point Software: SmartCenter Tools has a way to print it out, but it won't work pre-FP3.
