Upgrade tomcat 7 to 10.
Hi,
i need upgrade my tomcat server from 7 to 10. I don't saw in internet
nothing about that. Commonly i upgraded in steps, 7 to 8, 8 to 9 and 9 to
10.
Are there a problem upgrade from 7 to 10?

As what Christopher Schultz mentioned, "including switching package
names", i.e. from javax to jakarta.. when I did the webapp migration
to tomcat 10, I had to make all the libraries to reference jakarta
though, including taglib-mailer, jsp and so on.

Yes, it is! but not in a production environment. I want to upgrade in only
one shot.

I suspect you should be able to upgrade your Tomcat from 7 to 10 in one
shot, but you might want to go from 7->9 and wait a little on 10.
Why?
Tomcat 10 is significantly different because it implements a new version
of the servlet and related specifications, including switching package
names, etc. There *is* an automated conversion tool that can be used at
deployment-time to convert your pre-Jakarta-EE application to a
Jakarta-EE application, but you might not want to trust it immediately
in production without a whole lot of testing. So I recommend Tomcat 9 at
first.
YMMV
Something that is critically important is that, when upgrading, you
don't even try to re-use the existing server.xml file you have for your
Tomcat 7 installation. Instead, look at the differences between your
current server.xml file and an unmodified one from the original
distribution of Tomcat 7, and make some notes. Then, make similar
changes to the original server.xml file from the new Tomcat.
