Hello.
Currently Jira Software 8.5 is the available LTS release. I was thinking about upgrade to it from 7.13.12. But now Jira Software 8.13 was announced as next LTS release. Is it recommended to wait? The EOL for 7.13 is 28/Nov/2020.
We can wait, but it depends on, when version 8.13 will be available.
