Export from Apex 3.2 and import to Apex 4.0

Question

I apologize if this has been asked before (and I am sure it has).
We are about to move all our Apex/Oracle apps to a server where Apex 4.0 is installed. Our current Apex version is 3.2. My question is can we export from Apex 3.2 and import in Apex 4.0 and expect everything to work (assuming it all works fine in Apex 3.2 and all Oracle objects were moved properly to the new server , both servers have Oracle 11g).

Answer 1

I am having trouble finding "update application" under any of the utilities.
Also one of my applications gives me the following error when I try to import it from Apex 3.2. to 4.0
ORA-20001: GET_BLOCK Error. ORA-20001: Execution of the statement was unsuccessful. ORA-02290: check constraint (APEX_040000.WWV_FLOW_WS_RPT_CHART_AGG_CK) violated <pre>begin wwv_flow_api.create_worksheet_rpt( p_id => 24053127534342788+wwv_flow_api.g_id_offset, p_flow_id=> wwv_flow.g_flow_id, p_page_id=> 60, p_worksheet_id => 24052412232342516+wwv_flow_api.g_id_offset, p_session_id => null, p_base_report_id => null+wwv_flow_api.g_id_offset,
I have no clue how to fix that.
