Hi support,
I'm upgrading an old Confluence 3.4.6 to the current one. The first step, if I understand, it's to upgrade in the version 3.5.17. I followed the instructions in https://confluence.atlassian.com/display/CONF35/Upgrading+Confluence+Standalone+Distribution, without customization part. But I get a error page in browser, no error in log files. I don't know how I can do.
Error description :
Upgrade failed. Please consult the system logs for details. You will need to fix these problems, restore your database and confluence home directory to the pre upgrade state. Then retry the upgrade.
Server configuration : (Migration test server, an exact copy from the production one with VMWare, only server name was changed to acces)
* 3.5.17 standalone
* local postgrest DB
* OpenLDAP authentication
Thanks for your help.
