=== New migrate to data tiers routing API

7.14 introduces the {ref}/ilm-migrate-to-data-tiers.html[migrate to data tiers
routing API]. You can use the API to switch indices and ILM policies that use
attribute-based allocation filters to data tiers using
{ref}/modules-node.html#node-roles[node roles]. This lets ILM automatically move
data stream indices between tiers during phase transitions. Data tiers also give
you access to additional ILM features, such as partially mounted indices and the
frozen tier.
