Currently I'm using kibana v7 I have custom kibana system index like ".abc-kibana" what should I do when upgrade from 7.17 to 8.14 ? Is kibana 8 automatically detect old index to migrate ?? ---

Hi @haopv, This is how [saved object migration](https://www.elastic.co/guide/en/kibana/current/saved-object-migrations.html#upgrade-migrations-process) works. Also you can follow the complete process for [kibana upgradation](https://www.elastic.co/guide/en/kibana/current/upgrade.html)
