.Failed upgrades to 8.8.0 can cause bootlooping and data loss
[%collapsible]
====
*Details* +
The 8.8.0 release splits the `.kibana` index into multiple saved object indices. If an upgrade to 8.8.0 partially succeeds, but not all the indices are created successfully, {kib} may be unable to successfully complete the upgrade on the next restart.
This can result in a loss of saved objects during the upgrade. This can also leave {kib} in a bootlooping state where it's unable to start due to `write_blocked` indices.
*Impact* +
The 8.8.1 release includes in {kibana-pull}158940[a fix] for this problem. Customers affected by a failed 8.8.0 upgrade should contact Elastic support. For more information, see the {kibana-issue}58733[related issue].
