It's time to start preparing to upgrade my Confluence instances again. I'm hoping to upgrade to 5.6.6 from 5.3.4 but will take recommendations from the community on the best path forward. I've reviewed all the release notes and upgrade guides and haven't noted any gotchas but one of you may have additional insight or recommendations.
I have 2 large Confluence instances running 5.3.4 (one running Postgres 8.4.20 & one running Oracle 11.2.0.2.0) that are linked to a JIRA instance running 6.1.7 & JIRA Agile 6.3.6.1. We do have a few custom plugins that we rewrote for the jump from 3.5.17 to 5.3.4. I'd prefer to not upgrade JIRA/JIRA Agile at the same time.
Looking forward to hearing your recommendations & thanks!
