Uninstalling iFOR Version 4
iFOR version 4 requires converting licenses from the previous version to
a new format. If you un-install version 4 and then reinstall version 3.0.x,
you will not be able to use the new version 4 database. You can restore
the copies of the version 3.0.x database files that were saved with the
"V3" extension in the /var/opt/ifor directory. This can be done by
renaming these files and removing the "V3" extension. Doing this,
however, will lose any licenses that were added when version 4 was
installed.
