it's possible with an addon like Jira Suite Utilities or Jira Misc Workflow Extensions. For Jira Misc Workflow Extension, you can follow this documentation for example : https://innovalog.atlassian.net/wiki/spaces/JMWEC/pages/94142540/Transition+linked+issues
Let me know if this helps,
Also possible with the various scripting tools. (Scriptrunner, powerscripts)
One thing to be aware of
If you are doing it with a post function in the transition, it happen "in real time" ie, the other issues will be closed during the post function excution.
If you use Automation for Jira, it happens "out of band" Meaning that Automation listens for the close event which happens at then end of your post function, and then tries to take actions.
There are plusses and minuses for both methods, but you should be aware of the difference.
