Is it safe to/should I remove older versions of plugins?

[Ben Longman]

Looking in /var/atlassian/application-data/jira/plugins I see this:

[root@cdedev1-iajira plugins]# find . | grep jira_git_plugin
./installed-plugins/jira_git_plugin-2.5.20.jar
./installed-plugins/plugin.796110448874046358.jira_git_plugin-2.12.5.jar
./.osgi-plugins/transformed-plugins/jira_git_plugin-2.5.20_1421970013000.jar
./.osgi-plugins/transformed-plugins/plugin.796110448874046358.jira_git_plugin-2.12.5_1509677901000.jar
[root@cdedev1-iajira plugins]#

Is it safe to, and should I, remove the 2.5.20 version of the plugin?

1. It's safe to delete plugins from the folders (./installed-plugins and ./.osgi-plugins/) only, when JIRA is stopped.

2. Usually .osgi-plugins is recreated on the start of JIRA, so you can delete ./.osgi-plugins/transformed-plugins fully.

3. Yes, I advise to remove ./installed-plugins/jira_git_plugin-2.5.20.jar.
Rarely we see old version of Git Integration add-on run on JIRA instead of the latest one.  A removal of old versions helps.
