Install listenerStart Error

Hi 

 

I did a manual update of Confluence from 5.4.4 to 5.10, I experienced some issues with the plugins so I need to revert back to the old version, but when I point it to the 5.4.4 version it fails to start with the following errors:

2017-04-28 08:30:25,798 INFO [main] [com.atlassian.confluence.lifecycle] contextInitialized Starting Confluence 5.4.4 [build 4733 based on commit hash f235dd088df5682b0560ab6fc66ed22c9124c0be]

I notice the error "Abandoned connection cleanup thread" which seems to be causing this, but can anyone tell me how to resolve it?

Did you restore the pre-upgrade data before going back to the older version?

Sorry could you please explain how to do this?

Maybe a little more information, I downoaded the 5.10 not the installer, extracted it to /opt where the 5.4.4 directory is also, then changed a symlink named atlassian-confluence so the init script can start confluence but due to issues with plugins and a time constrain then I decided to revert back.

Changed the symlinink back to 5.4.4 started confluence but it stops on this error.

When you try to move to a newer version, Confluence upgrades the data.  The data for 5.10 is not valid for 5.4, so you can't just swap back.  There is no downgrade route, you need to restore the data from a backup.

I suspect your 5.4 is failing simply because it's finding bits of 5.10 in the data and possibly in the installation.

Ok but if it's not starting then how can I take the export I did and import it? 

And many thanks for taking the time looking at this.

You'll need to install a clean empty copy of 5.4, then you'll be able to restore the export into that.
