*Details* +
64+
In 8.x, {es} will only read indices created in version 7.0 or above. An 8.x node
65+
will not start in the presence of indices created in 6.x or earlier versions of
66+
{es}.
67+
68+
*Impact* +
69+
Before upgrading to an 8.x version, reindex any index created in 6.x or earlier
70+
versions with {es} 7.x. If you no longer need the index, delete it instead.
71+
You can use the get index API to check the {es} version in which an index
72+
was created.
