Saved IRs lost when installing a new version of an application

Question

Hello,
is there any documented solution for the following problem:
The client has saved some IR. Now a new application version is installed via script using the apex_application_install api.
The application_id of the exported version and the imported version are the same, i.e.200. The workspace_ids aren't the same.
So all reports the client saved are lost.
I found the solution http://www.talkapex.com/2009/10/saving-saved-interactive-reports-when.html
and adapted it a bit because it didn't work for me.
BEGIN
  FOR x IN (SELECT a.ID, a.name, a.session_id,a.updated_on,
                   b.interactive_report_id
              FROM apex_040000.wwv_flow_worksheet_rpts a,apex_application_page_ir b
             WHERE a.flow_id = 200
               AND a.page_id = b.page_id -- Linking is done via the page so please be aware of any IR page changes
               AND b.application_id = a.flow_id
               AND a.worksheet_id != b.interactive_report_id
               and a.status = 'PRIVATE'
               and a.session_id is null
               and A.UPDATED_ON = (SELECT max(aa.updated_on)
                  FROM apex_040000.wwv_flow_worksheet_rpts aa
                 WHERE aa.flow_id = a.flow_id
                   AND aa.page_id = b.page_id -- Linking is done via the page so please be aware of any IR page changes
                   AND aa.worksheet_id != b.interactive_report_id
                   and aa.status = 'PRIVATE'
                   and aa.session_id is null
                   and aa.name=a.name)
               and not exists(select aa.id from apex_040000.wwv_flow_worksheet_rpts aa where aa.flow_id = a.flow_id
                   AND aa.page_id = b.page_id -- Linking is done via the page so please be aware of any IR page changes
                   AND aa.worksheet_id = b.interactive_report_id
                   and aa.status = 'PRIVATE'
                   and aa.session_id is null
                   and aa.name=a.name))
  LOOP
    UPDATE apex_040000.wwv_flow_worksheet_rpts
       SET worksheet_id = x.interactive_report_id
     WHERE ID = x.ID;
  END LOOP;
END;
commit;This works correctly but this isn't documented and must be run as SYSTEM or a user with SYSTEM level access.
Is there any other solution?
I also tried this http://joelkallman.blogspot.com/2010/07/where-did-my-saved-interactive-reports.html
(apex_application_install.set_offset( p_offset => 1573299003458268419 );)
but couldn't make it work.
I use APEX 4.0.2.
Thank's.

Answer 1

The script posted by Kirsten did work for me on APEX 4.1 (just need to change APEX Schema to apex_040100). Thanks a lot for sharing.
But I have same question - is this approach save to restores users' private reports?
If this is that easy, why it is not included in the application installation?
