I recently upgraded an application Struts 1.2 to 1.3. The actual
changes needed to upgrade are quite easy to implement if you have a
decent search and replace tool (these changes being detailed on the
previously mentioned wiki page).
In addition, if your project makes use of numerous Jar libraries (like
Struts, Spring, Hibernate etc.) I would recommend using Maven for
assembling the necessary Jar files for your upgraded application.
If you've not used Maven before it is worth investing a little time to
learn it (it doesn't take long). Essentially you create a Maven XML
project file (POM) detailing the Struts version and any other major
Jar libraries that you are using (you can cut and paste some of the
configuration details from http://www.mvnrepository.com/).
Maven can then be used to download the appropriate Struts Jar file,
the libraries that Struts depends on, any other libraries and the
libraries on which they depend. It will also resolve library version
conflicts that might arise.
Even if you are not using Maven as your build tool, you can still make
use of it inside Ant builds in order to do dependency management
(which incidentally is only one aspect of what Maven can offer).

For applications of this nature Maven will make future Jar upgrades easier.
