Hello WMCS users,
Just a heads-up that we'll be migrating the cloudelastic hosts (aka the CirrusSearch elasticsearch replicas)[0] from Elasticsearch to Opensearch starting this week.
From a user point-of-view, nothing is expected to change (same URLs, same API calls, same level of access, etc), nor do we expect any service interruptions. However, if you do notice any issues, feel free to ping us in #wikimedia-search or respond here. You can follow https://phabricator.wikimedia.org/T387904 for more details.
Best,
