I am trying to recover an old Confluence database and have got as far as determining that the database was created using Confluence 5.6.4. When I install v5.6.4, it successfully loads the database (i.e. it doesn't crash or complain about the build used to create the database) but the old database assumes that users will be authenticated via JIRA. Suddenly I have no way to login to Confluence so can't export the data or even view it. The JIRA server has been moved recently so I doubt that the information held, in Confluence, about the JIRA instance is correct.
It seems that no-one predicted this problem or they would have exported the data from Confluence before moving the servers. How can I override the user configuration to get into the database and export the data?
Thanks.
