# Add new servers

|   |                                                                                                                                                                                                                                                                                                                 |

|   | If either of the following are true, begin with the [upgrade documentation for DS 7.5](https://docs.pingidentity.com/pingds/7.5/upgrade-guide/preface.html) instead:- The deployment includes DS 6.5 or earlier servers.

- The deployment hasn't yet moved to the DS 7 security model based on deployment IDs. |

Otherwise, [Install the new servers](../install-guide/preface.html) and rebuild indexes as necessary:

1. [Install the new server](../install-guide/preface.html) with settings compatible with those of the existing servers.

   Learn about changes since the deployed release in [Incompatible changes](https://docs.pingidentity.com/pingds/release-notes/changes.html).

2. If existing servers use [change number indexing](../config-guide/changelog.html#ecl-configure-changenumber-indexer), configure the settings on the new servers to match the same settings on the existing servers.

3. Rebuild untrusted `mail` indexes for the change to the `mail` attribute schema definition to allow UTF-8 characters.

   The definitions for DS 7.3 and later allow UTF-8, whereas earlier versions allow only ASCII. The change does not affect the data, but does affect `mail` indexes.

   For details, refer to [Automate index rebuilds](../config-guide/idx-config.html#automate-index-rebuilds).
