I am trying to use the Upgrade Assistant provided by kibana.
I have to upgrade one of my indices to version 6.8 because it is created with version 5.x before I can upgrade my cluster to version 7.
Last night I started the migration process but after 10 hours and around 66% the process just errored with this message:
"TypeError: _primary_term from Elasticsearch must be an integer"
What am I supposed to do with such a message? Is one record damaged/different? Can the upgrade assistant not just ignore such entries?
Is there a way to get more information about this error? I couldn't find any with Google.
The index size is around 10GB and contains mainly simple log entries.
I am running on hosted elastic cloud.
Thanks in advance,
