## Upgrading from version 1.1 to 1.2

The 1.2 release is a drop-in replacement for 1.1 with no data migration
required - just download and install the
[1.2 packages](https://portal.influxdata.com/licenses) and restart the processes.
We recommend that you review the
[Changelog](/enterprise/v1.2/about-the-project/release-notes-changelog/) prior
to upgrading.

Because of
[a small change](/enterprise/v1.2/about-the-project/release-notes-changelog/#features)
to the data node's configuration file, installing the new data package will
prompt you to either keep or overwrite your current configuration file.
We recommend that you keep a copy of your current configuration file and
migrate any customizations to the new 1.2 configuration file.

## Upgrading from versions prior to 1.1 to 1.2

Please review the [1.1 documentation](/enterprise/v1.1/administration/upgrading/)
if you're upgrading to version 1.2 from a version prior to 1.1.
