we are facing error migrating from elk.5.alpha4 to official elk.5. in a specific way, Kibana doesn't show any result even thought it shows all the fields in the "Index Patterns" tab.
is there any specific procedure to update it?
There is absolutely no guarantee that anything done in an alpha version can be upgraded.
You probably have to rebuild that from scratch.
BTW your question should go to #kibana instead I think.
