Space export does not export restricted pages.

I am attempting to upgrade Confluence 1.4.4 to 2.2.9.

We have a large confluence installation with > 100,000 pages.

I cannot do a complete backup/or restore so I have been attempting to export individual Spaces. However any page which has been restricted ( plus any children of that page ) is not exported.

I have checked the export file and the page has not been exported into the file.

It seems possible that the export honours the permissioning model and disregards the fact that I am the administrator.
