Issue Summary

The External System import for Jira Cloud has a question mark icon in the top right of the page, that is intended to take you to Atlassian's online documentation of how this importer functions. The page you can see this on is:
example.atlassian.net/secure/admin/ExternalImport1.jspa

If you click the link it takes you to:
https://confluence.atlassian.com/display/JIRA/Migrating+from+Other+Issue+Trackers

Which currently redirects to
https://confluence.atlassian.com/adminjiraserver073/migrating-from-other-issue-trackers-861253679.html

The problem with this is that Jira 7.3 has importer options that have not been possible in Jira Cloud for months or years (Bugzilla importer, redmine importer, asana importer, etc)

It would be much better if this link just took admins to a page such as https://confluence.atlassian.com/adminjiracloud/migrating-from-other-issue-trackers-884344525.html

Steps to Reproduce

1. Goto the external system importer as a Jira admin, URL /secure/admin/ExternalImport1.jspa
2. Click the ? in the top right to get help with documentation

Expected Results

Takes you to documentation about Jira Cloud importer options

Actual Results

Takes you to Jira Server 7.3 documentation that doesn't apply in most cases.

Workaround

Admin will have to manually find the correct documentation that applies to his/her platform, such as https://confluence.atlassian.com/adminjiracloud/migrating-from-other-issue-trackers-884344525.html in the case of Jira Cloud admins that need help here.
