When you are upgrading IDS from one fix pack level to
another in the same product version, you can install the
product in the running database server installation
directory. You also can overwrite an existing installation
for training or specialized technical needs. Take all
necessary backup precautions before upgrading with this
method. It is recommended that most users follow the
IBM Informix Migration Guide for version-to-version
	upgrades and migrations.

Multiple Copies of IBM Informix Dynamic Server on the	“Multiple Copies of IDS on One Computer” on page 1-2
	Same Windows Computer
In version 11.10, you could not install and run multiple
copies of the same version of IDS on the same Windows
computer. Now you can do so by using the graphical
user interface or by supplying installation parameters in a
file to perform a silent, non-interactive installation.
If the installation application detects that the same
version of IDS is already installed, you can choose to
install a new copy in another directory or you can choose
to modify the existing installation.
