Links are broken after cloud to cloud migration

Problem Definition

When moving Jira and Confluence from one cloud instance to another cloud instance ,the new environment has different URLs, which affects the issue link in Jira and page links in Confluence as they rely on page IDs and base URLs which has been defined earlier on the older source environment.

This impacts all migration methods via CSV/XML export/Import or via C2C migration tools

Suggested Resolution

Confluence/Jira links in destination cloud need to be updated as per the URLs in the destination cloud. 

Temporary Resolution

In this case you contact Atlassian support by logging a request in support.atlassian.com and ask them to apply the workaround for this issue.

Some of the links can be fixed as per the boundaries detailed at https://confluence.atlassian.com/confkb/after-a-successful-server-to-cloud-migration-url-links-are-broken-in-the-new-cloud-instance-1077781093.html (Article calls out Server to Cloud migration, but works for cloud to cloud migrations too)
