Internally Turbine 3.0 will be very different than Turbine 2.0. Turbine 3.0
will not be a drop in replacement but the TDK is evolving to include
migration tools which should make the process relatively painless. As more
people migrate applications and run into problems the migration process will
become more complete.
The use of pull tools will definitely help your migration. If you can avoid
creating individual modules than you will be far better off. I believe that
an app using pull tools will a few base modules will be relatively easy to
migrate.
What will probably bite many people in the ass will be the formation of an
API in Turbine 3.0. In Turbine 2.0 things are pretty loosy goosy and people
have nailed things on to the Turbine 2.0 structure to accomplish something
because it wasn't possible without changing a lot of code, or there's ten
ways to do the same thing. I hope that standard ways to accomplish certain
tasks will emerge. The entire system will be pluggable from one end to the
other so hopefully what we will end up with is set of interfaces with a
default implementation that should cover most things in a standard
application

I really believe that the process of migration can mostly be passed off to a
process in the TDK. Between a combination of adapter code and some migration
tools that most people will be able to move there apps forward in less that
a days work. The migrator will catch 95% of the cases and as more issues
come to light they can be accounted for in subsequent versions of the
migrator.
