After upgrade from 2018.1 to 2018.1.2, we got the error of DataServiceFailure frequently. It happens when we do data blending with large datasources.
While we are asking tableau technical support to solve the issue, we would like to downgrade the server as an immediate solution.
I noticed that there is a similar documentation for window:
But I don't know how to do that in linux.
We would like to downgrade the server version but keep the content we added/edited after the upgrade. What we can think of is to export the current site, and then import to the downgraded server.
May I ask what is the best way for doing that?
