This change also updated the deprecation warning on all rollup pages from Rollups will be removed in a future version. Use <<downsampling,downsampling>> instead. to Rollups will be removed in a future version. Please <<rollup-migrating-to-downsampling,migrate>> to <<downsampling,downsampling>> instead..
Removes `testenv` annotations and related code. These annotations originally let you skip x-pack snippet tests in the docs. However, that's no longer possible.
Relates to #79309, #31619
Redeprecates the `/_xpack/rollup` endpoints in favor of `/_rollup`.
When we cleanup the rollup in a cluster containing 6.x nodes we need to
use `/_xpack/rollup` instead of `/_rollup` because the 6.x nodes don't
know about `/_rollup`. In those cases we must ignore the deprecation
warnings that the 7.0 node will return for the end point.
Closes#36044
