Remote links fail to load after any confluence import due to changing appId and pageId

Summary

After performing a JIRA Site Import and a Confluence Import from another instance the remote links from JIRA to Confluence display 'Page Failed to load' as both the appId and pageId have changed.

Steps to Reproduce

1. Create instance-a containing JIRA Cloud and Conlfuence Cloud
2. On instance A create an issue and then refer to that issue from a Confluence page
3. Take a site backup and space backup of JIRA and Confluence
4. Import the JIRA Site backup into instance B
5. Import the Confluence space backup into Instance B.
6. View the JIRA Issue on instance B

Expected Results

A remote link to the page on instance B exists.

Actual Results

The remote link on instance B says:

Page Failed to load

If you check the database the pageId and appId will not match the space export.

Workaround

As both the pageId and appId have changed it's nearly impossible to map the pages back in any automated fashion. Recreating the links will be your best option.
