=== Update {transform} API
[subs="attributes"]
++++
Update {transform}
++++
Updates certain properties of a {transform}.
[[update-transform-request]]
==== {api-request-title}
`POST _transform//_update`
[[update-transform-prereqs]]
==== {api-prereq-title}
If the {es} {security-features} are enabled, you must have the following
built-in roles and privileges:
* `transform_admin`
* `manage_transform` (the built-in `transform_admin` role has this privilege)
* source index: `read`, `view_index_metadata`
* destination index: `read`, `create_index`, `index`
For more information, see <> and <>.
[[update-transform-desc]]
==== {api-description-title}
This API updates an existing {transform}. The list of properties that you can
update is a subset of the list that you can define when you create a {transform}.
When the {transform} is updated, a series of validations occur to ensure its
success. You can use the `defer_validation` parameter to skip these checks.
All updated properties except description do not take effect until after the
{transform} starts the next checkpoint. This is so there is consistency with the
pivoted data in each checkpoint.
[IMPORTANT]
====
* When {es} {security-features} are enabled, your {transform} remembers which
roles the user who updated it had at the time of update and runs with those
privileges.
* You must use {kib} or this API to update a {transform}. Do not update a
{transform} directly via `.transform-internal*` indices using the {es} index API.
If {es} {security-features} are enabled, do not give users any privileges on
`.transform-internal*` indices. If you used {transforms} prior 7.5, also do not
give users any privileges on `.data-frame-internal*` indices.

`defer_validation`::
(Optional, boolean) When `true`, deferrable validations are not run. This
behavior may be desired if the source index does not exist until after the
{transform} is updated.

TIP: In general, it’s a good idea to use a field that contains the

you might need to set the `delay` such that it accounts for data transmission
delays.
