Multiple, but if you like to do it without any extra tools you'll have
to cheat a little.

One way to do that is to take /etc/setup/installed.db from the old
system an drop it to the same place in the new system, then run
setup.exe and "reinstall" all packages.  You'll have to re-do all
customization steps that wereN#t done as part of the installation
itself, but you seem to know that already.
