Spring 2.0 is, well, 99.9% backwards compatible. We did clean up some areas
of the framework: Some deprecated features that have been removed or
replaced, but hardly anything that should surprise if you're coming from
1.2.8.
If you happen to use some of those few features that changed, you will
immediately notice on recompiling your application, or on application
startup at the latest. Once the application is up and running, you shouldn't
see any surprises.
Mixing and matching individual Spring jars from different versions is not
supported. If you decide to give Spring 2.0 a try, take all relevant Spring
2.0 jars and drop them into your application: Then recompile, restart and
see what's happening... The chances are high that it's simply gonna work out
of the box.
Also, don't you have to upgrade the application anyway once you deploy new
application features such as JMX notifications? It's usually straightforward
to upgrade the Spring jar in one go then... There is no need to update
Spring for applications that you keep as is; you would just need to update
if a new part actually uses Spring 2.0 features.

Subject: Re: [Springframework-developer] Spring v1.2.8 MBeanExporter
addingv2.0Notification feature
The Sakai project that I am working on is quite big and there are plans to
upgrade to Spring 2.0 with the next major release. However a lot of schools
will still use an older version of Sakai, which uses spring v1.2.8.
Is Spring v2.0 fully backwards compatible with v1.2.8? For example, are all
the default bean values the same if they haven't been specifically defined?
Is it possible to just use the spring-jmx-2.0.x with spring-core-1.2.x etc.?
Best,
