For the nRF54L and nRF54H Series, use the :ref:`Zephyr Memory Storage (ZMS) <zephyr:zms_api>`.

-----------------------
168+
169+
The following are the changes required to migrate your applications to the |NCS| v2.9.0-nRF54H20-1-rc3.
170+
171+
ZMS backend
172+
+++++++++++
173+
174+
The support for the backend for Zephyr Memory Settings (ZMS) has been updated.
175+
This update does not affect the ZMS Zephyr API.
176+
177+
Deprecated ZMS Kconfigs
178+
+++++++++++++++++++++++
179+
180+
The following ZMS Kconfig options are deprecated:
181+
182+
* ``CONFIG_SETTINGS_ZMS_NAME_CACHE``
183+
* ``CONFIG_SETTINGS_ZMS_NAME_CACHE_SIZE``
184+
* ``CONFIG_ZMS_LOOKUP_CACHE_FOR_SETTINGS``
185+
186+
New ZMS backend defaults
187+
++++++++++++++++++++++++
188+
189+
The ZMS settings backend now defaults to using the entire available storage partition.
190+
To customize the partition size used, complete the following steps:
191+
192+
1. Set ``CONFIG_SETTINGS_ZMS_CUSTOM_SECTOR_COUNT`` to ``y``.
193+
#. Set the number of sectors used by the ZMS settings backend using the ``CONFIG_SETTINGS_ZMS_SECTOR_COUNT`` Kconfig option.
194+
195+
For example::
196+
197+
CONFIG_SETTINGS_ZMS_CUSTOM_SECTOR_COUNT=y
198+
CONFIG_SETTINGS_ZMS_SECTOR_COUNT=8
