If the
.watches
index was created in 5.6 and is still a concreteindex, rather than an alias for
.watches-6
, that means that it was notproperly upgraded with the Migration Upgrade API before upgrading to
Elasticsearch 6.x. In this case, calling the Migration Upgrade API is
needed to resolve the problem with the
.watches
index, as a simplereindex will not.
This isn't going to be a common case, as Watcher will not run properly
in this situation, but we should handle it and notify the user of the
correct action, just in case.
