We would like to upgrade to the latest version or at least N-1(6.6.12 to7.4.0) version.
1. What is the migration path? I.e., can we directly migrate from current version to the latest version?
2. Or do we need to plan a staggered update, where we upgrade to each version at different times to upgrade to the latest version?
3. We also use Jira and BB, can Confluence be upgraded without impacting any functionality between the three?
4. OR is there a cross-dependency that we should plan to upgrade all three at the same time? (I would like to avoid upgrading all three at once, if possible)
