This will be a time-consuming process. NetBeans can help you figure out
new versions of libraries in POM files and will mark out deprecated
classes. Other than that it's just tinkering from my experience. The
most time-consuming part will probably be updating Hibernate and Spring
if you use them. If you want to upgrade to the latest libraries, you
will have to go through the javax → jakarta conversion. Hibernate 5 to 6
is a big step too because you have to re-write all your DAO to new JPA
Criteria API. Other then using GPT I don't know any tools for that (GPT
is mostly good for that though). If you are lucky you are not using any
discontinued libraries (we had to go through removing Bobo Facets from
our search).
To be honest, even if you have good test coverage, this will probably
take months for a large application. Just figuring out all the small
things that need updating is time-consuming. You will also need to
update to Tomcat 10 to use Jakarta, which might be a problem for your
DevOps/admins (it may require new systems).
If you will choose to hold back Tomcat 9 can be used with javax and
Hibernate 5 still can handel both old and new HB Criteria APIs.
Unfortunately, *Spring 5 already has security bugs* (CVE) and will /not/
receive free updates, so the upgrade from javax to jakarta is inevitable.
Good luck,

Hi
I have a Maven-based client/server application, which is written in Java 8.
The client is using JavaFX and communicating with the server using REST calls.
I need to update to a current Java release.
I use NetBeans since Version 7 for different employers.
How can NetBeans help here?
Thanks for your help.
Regards
Claus
