Upgrade XWiki 11 to 14 or 15

I tried to update XWiki 11 to XWiki 14 (Docker) but it didn’t work and I got an error (below). Tell me, is it possible to update XWiki from 11 to 14 through Docker? How to do it right?

Is there a step-by-step update guide?


Error: Cannot find /usr/local/tomcat/bin/setclasspath.sh

The doc is at xwiki-docker/README.md at master · xwiki/xwiki-docker · GitHub

The mentioned error occurs because your docker version is old. So, besides following the documentation mentioned above on how to upgrade XWiki, you also need to upgrade docker: Install Docker Engine on Ubuntu | Docker Docs

Ok. Thanks.
Problem solved.

Cool. What was the problem?

Docker version. It was 18.XX. I up docker containers on docker 20.XX
