I noticed there's a lot of old, unused files and database tables left after upgrading from EasyBlog 3.9.x to 5.0.x. I'm trying to clean up all the unnecessary .backups, /media/foundry/ old version scripts, and /media/com_easysocial/ files left behind. There are also several database tables from old versions that aren't added with a fresh, new EasyBlog 5 install. Of the following, which can I safely delete?

Old version database tables not on new EB 5 install:
easyblog_blogger_subscription
easyblog_category_subscription
easyblog_drafts
easyblog_feeds_history
easyblog_fields_groups
easyblog_fields_values
easyblog_hashkeys
easyblog_post_subscription
easyblog_site_subscription
easyblog_stream
easyblog_team_subscription
easyblog_trackback
easyblog_trackback_sent

Thank you!
Richard
