During the upgrade to Alteryx 11 does the Mongo DB get upgraded to a new version?
We have had a situation where the install had to be reversed and are getting the error:
From event viewer I have this error: Error - Failed to construct Gallery daemon process, process exited code <0>
From Gallery Log I find this error: Database version 18 is newer than the code version 15. Please upgrade Alteryx cloud.
If this is the case what is the process for rolling back? Create a clean install and restore the DB from the backup?
@paul_houghton The version of the embedded MongoDB hasn't changed with the 11.0 release and is still version 3.0.4. However, there are significant changes to the internal database structure. Because of these changes the the internal database version was updated, and is not compatible with prior versions. As such in order to roll back to an older version you will need to uninstall version 11, remove the current MongoDB, install the older version you want to use, and then restore the database from a backup made prior to the 11.0 update. If a backup isn't available prior to the update your only options would be to start over, or continue using 11.0.
Can you provide some feedback on why the roll back is needed?
@mbane1 This actually happens more than you would think. The good news is you should be able to just install the server version, and everything should be fine. During the installation of server it will remove the current Designer installation and reinstall server including Designer. Once completed the service should come back up and connect to your database and start Gallery as if nothing changed. If it doesn't come back up properly send and email to support and we will be happy to assist you in troubleshooting.
@mbane1 You can try to, but the upgrade to 11 may have migrated part of the database in order to support some of the new features. If so you may run into issues with 10.6 and it may refuse to start properly. You would be better served by installing version 11 of server. Did you backup the database prior to the upgrade. If so you can install 10.6 and restore that database backup.
