I know that on DB2 V8.2 (on Linux) it wasn't possible to "upgrade" without
reinstalling.

But on V9.1, can I initially install Workgroup, and then if we need
additional functionality can we buy Enterprise and apply the keys to an
existing Workgroup installation ?

Or do we need to reinstall ?

I know you can't upgrade Express-C to a "paid" version, but that may just be
a special case.

I wonder if it is possible to install ESE Try and Buy ESE, and then install
the WSE license, and only create WSE instances? Then when you get an ESE
license, you already have the ESE code installed. I don't know if this
works.

Well ... not entirely true. You can install ESE over WSE, and now you have
both. Uninstall/reinstall is often easier than install/partial-deinstall.

You can install WSE in one location, and ESE in another. And you can use
db2iupdt to jump the instance from the WSE copy to the ESE copy.

Nope. You'll still have an ESE try&buy, and it will stop working after the
time limit runs out.

I know that you can install ESE Try and Buy, and then install a valid ESE
license.

My understanding was so far that you just had to roll in a new license (also
on V8) to go from WSE to ESE, for example. After all, it is the same code
base. Is this not correct?

Absolutely.

No. ESE has more code than WSE (the DPF support code), for example. Most
of the code is the same - ESE has an extra MB or three of actual code.
