I upgrade kibana from 7.11.1 to 7.12.0 the process has been finished the index has green status and I have access to kibana but I check .kibana_task_manager_7.12.0_001 index and looks like it still reindex

health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open .kibana_task_manager_7.12.0_001 a6xg7wAJTWCoFUitL7ZAas 1 1 10 41463 9.5mb 3.8mb
green open .kibana_task_manager_1 Qi6DrGASQMeYGVm1fT7GGw 1 1 9 48267 4.8mb 4.7mb

how can I know that .kibana_task_manager_7.12.0_001 has been migrated and it safe remove .kibana_task_manager_1

Hi, is Kibana starting up successfully? Are there any error logs you are seeing?

Hi, thank you for reply,

I confirm that kibana started up successfully, there isn't any error in kibana logs, I only saw .kibana_task_manager_7.12.0_001 index is keeping increase, my first assumption is that .kibana_task_manager_7.12.0_001 was being reindexed from .kibana_task_manager_1 and keeping reindex it after kibana came up, but now I see that .kibana_task_manager_7.12.0_001 is keeping increase even more than .kibana_task_manager_1. My assumption is that .kibana_task_manager_7.12.0_001 index is increasing as normal behaviour and it isn't related with reindex from .kibana_task_manager_1

Hi, I wouldn't worry about the system indices like .kibana_task_manager* because they are internal implementation details that Kibana needs to manage itself to work properly. Fortunately, it looks like this is a very small index that isn't costing much storage space.

I'll check with the Alerting team here at Elastic to see if there was some kind of bug that made cleanup of the old index fail.
