== Indices mix index allocation filters with data tiers node roles to move through data tiers
|
|
|
|
Elasticsearch standardized the implementation of https://www.elastic.co/blog/elasticsearch-data-lifecycle-management-with-data-tiers[hot-warm-cold architectures]
|
|
to <<data-tiers, data tiers>> in version 7.10.
|
|
Some indices and deployments might have not fully transitioned to <<data-tiers, data tiers>>
|
|
and mix the new way of implementing the hot-warm-cold architecture with
|
|
<<shard-allocation-filtering, legacy>> based node attributes.
|
|
|
|
This could lead to unassigned shards or shards not transitioning to the desired
|
|
<<data-tiers, tier>>.
|
|
|
|
In order to fix this follow the next steps:
