Add new servers

If either of the following are true, begin with the upgrade documentation for DS 7.5 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 and rebuild indexes as necessary:

Install the new server with settings compatible with those of the existing servers.

For changes since the deployed release, refer to Incompatible changes.
If existing servers use change number indexing, configure the settings on the new servers to match the same settings on the existing servers.
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.
