If your {ml} indices were created before {prev-major-version}, you must

If your {ml} indices were created in {prev-major-version}, you can:
|
|
|
|
|
|
|
|
|
|
* Leave your {ml} jobs running during the upgrade. When you shut down a
|
|
|
|
|
{ml} node, its jobs automatically move to another node and restore the model
|
|
|
|
|
states. This option enables your jobs to continue running during the upgrade but
|
|
|
|
|
it puts increased load on the cluster.
|
|
|
|
|
|
|
|
|
|
* Temporarily halt the tasks associated with your {ml} jobs and {dfeeds} and
|
|
|
|
|
prevent new jobs from opening by using the

When you disable upgrade mode, the jobs resume using the last model
|
|
|
|
|
state that was automatically saved. This option avoids the overhead of managing
|
|
|
|
|
active jobs during the upgrade and is faster than explicitly stopping {dfeeds}
|
|
|
|
|
and closing jobs.

|
|
* {stack-ov}/stopping-ml.html[Stop all {dfeeds} and close all jobs]. This option
|
|
|
|
|
saves the model state at the time of closure. When you reopen the jobs after the
|
|
|
|
|
upgrade, they use the exact same model. However, saving the latest model state
|
|
|
|
|
takes longer than using upgrade mode, especially if you have a lot of jobs or
|
|
|
|
|
jobs with large model states.
