Mixing code levels

Can you have muliple DB2 instances that are at different code levels on the
same computer? For example, can I have an instance of DB2 V8 and an instance
of DB2 V9 on the same Windows machine?

I know it is possible to have multiple DB2 instances on the same computer if
they are at the same code level. For example, I've read that you could have
two or more instances of DB2 V8 on the same PC. I just can't find anything
that says whether DIFFERENT code levels can code exist on the same PC.

Starting with v9, you can have multiple copies of DB2 - which include
same/different code levels. v8 can't handle this, so you can only have one
copy of v8 on the system. However, v9 can handle being with v8, so you can
have 1 v8, and multiple v9's.

Unix/Linux has always allowed different versions to co-exist (v7 with v8),
but multiple copies of the same version wasn't allowed until v9 as well.
(I largely don't count alternate fixpacks in v8.)

Starting with v9.1 this is possible (which implies you can have v8 and v9 on
the same box).
