We created a backup from our JIRA Cloud instance, making sure that it was a backup created for JIRA Server, as that was the target restore platform.
After restoring the backup on a new instance of JIRA Server, it pulled down pretty much all the projects (roughly 200), but is missing 14. I looked in the entities.xml file, and the projects that are missing are listed there amongst all the other projects.
And all Nextgen projects have been converted over to standard, so that is not the issue.
Can anyone think of any reasons why some projects wouldn't restore properly?
