I'm been tasked to migrate two enterprise applications (Java 7/JSP/Web 2.4) from Struts 1.2 to any version of Struts 2.x. The struts.apache site states Struts 2.5.20 is the "best available". Is there any recommendations/opposition on going all the way to 2.5.20 or should I stick with the latest prior version of 2.3.37? I'd appreciate any advice from those who have already been though this.
I will develop using Rational Application Developer 9.5.0.2.
Update: I just discovered, if you plan to use the struts2-struts1-plugin for your migration, 2.5 will not support this plugin. The latest release where this plugin is supported is 2.3.37.
