Similar to adding an index to an existing table, it could be necessary to replace one or more indices with a new one. To avoid a gap between dropping the old indices in a migration and adding the new one through ``AddMissingIndicesEvent``, it is possible to do both at once in ``AddMissingIndicesEvent``.
If none of the previous indices are found, e.g. because they were optional and not created yet, the replacement index will be treated as *missing index*.
.. note:: Make sure to not use the same index name for the new index as for old indices.
