We a few legacy apps that are on Struts 2.3.x, which is EOL now and we are looking to upgrade:
Questions:
1) Any pointers to migration guide from Struts 2.3.x to Struts 2.5.x?
2) Has anyone here has gone thru the efforts of migrating from Struts 2.3.x to Struts 2.5.x? what challenges did they come across and the solutions that helped them overcome those challenges?
Yes there are only 3 steps to do that
1. change you dependency in pom.xml of struts from 2.3.x to 2.5.x
2. Change the top tag in struts.xml from 2.3.x to 2.5.x
3. import struts-2.5.dtd instead of 2.3.dtd
You dont have to make any specific change since there is not a big difference between struts2.3 and 2.5
In addition to changes in Aakashdeep Singh's answer, The StrutsPrepareAndExecuteFilter was moved from org.apache.struts2.dispatcher.ng.filter to org.apache.struts2.dispatcher.filter.
You may want to refer the migration guide provided by Struts to ensure you don't miss anything.

I have an existing Vue 3.1 application. Since 3.2 came out I thought about upgrading it, but I can't find any documentation on how I should approach this. Maybe it's super simple and everyone knows how to do this... Everything I can find talks about upgrading from 2.x to 3.x or just starting from scratch with 3.2.
How should I go about going from 3.1 to 3.2
Thanks
I want to upgrade a Bootstrap 4 html/css website from Bootstrap 4.0.0 to the latest version (currently 4.3.1). I have googled this and only see instructions for upgrading from 3.x.x to 4.x.x. Can anyone point me in the right direction?
I agree with the lack of resources provided. However unlike the migration from 3.x.x to 4.x.x, there isn't any loss of component here. But you will see some nasty changes, that will just break things. I would suggest going through the examples for version 4.0.0 and then cross referencing them with the ones for 4.3.1 .This will not solve your problems but it will definitely point you in the right direction.
You found nothing, because there is not much to say (There should be no breaking changes).
So you simple need to update (replace) the library files (CSS, JS, Probably Fonts).
Note: In current days we use Package Managers like NPM and install our frameworks as Packages. In case of NPM, you can find bootstrap here.
What is the support for Dojo community support for Dojo 1.8.1 framework?
Our application use Dojo 1.8.1. What is the impact if we are advised to move to the latest framework ?
Dojo 1.x is pretty much "dead" in the sense that only minor maintenance is done.
Migrating to Dojo 2.x or higher from 1.x is not easy, as there is no out of the box migration path.
Of course you can wrap your Dojo 1.x widgets in Dojo 2.x, but then what's the point of using Dojo? Then you can also use another (more widely used) framework.
I don't want to bash on Dojo, as we use it extensively (and successfully) in our company, but the fact that there is no easy migration path to Dojo 2.x makes us want to transition into a more common framework eventually.

I developed the project in Bootstrap v3.0.1. Now some bugs were fixed and released the version Bootstrap v3.1.1. is there any guide to Migrating from Bootstrap v3.0.1 to Bootstrap v3.1.1.
I just backed up first, then copied the new files over the top of the old ones.
I had no problems.
The main point is BACKUP before you start.

Bootstrap follows Semantic Versioning, so v3.1.1 is backward-compatible with v3.0.1, except for one exceptional change regarding how the remote option of modals works, which happened in v3.1.0 (see the "Remote modal content" section of http://blog.getbootstrap.com/2014/01/30/bootstrap-3-1-0-released/ for details).
You can also read each of the relevant release blog posts (which have the changelogs) if you're really paranoid: http://blog.getbootstrap.com/
I'm learning struts 1. Ok, it's working.
And there is something I don't understand with tiles configuration.
On almost every tutorials on the net they say I only have to add the plugin org.apache.struts.tiles.TilesPlugin in the struts-config.xml.
But it's not working ... I have to add also the org.apache.struts.tiles.TilesRequestProcessor controller.
Why? Is there something wrong in my project? I'm using 1.3.10 struts dependencies.
