We planning to migrate Jira backlog from one cloud instance to another cloud instance but need to leave confluence to old cloud. There is reasoning behind this, but not going there in this question.
If we migrate issues to new cloud the links from Issues obviously works to old confluence if we have application link between them. but what happens to links from confluence pages to new Jira? What should be taken in consideration? Obviously they will break, but is there any easy way to keep them or bulk edit?
How about macros in Confluence. How should them be handled?
