### Additional Notes

#### Special dynamic configuration for Version 1.22.x-1.23.x
Temporal versions 1.22.x and 1.23.x support stream-based replication, but it was disabled by default. Since those versions were released, stream-based replication has been tested as more reliable than the poll-based replication that was the default in 1.22 and 1.23. When preparing for an S2C migration on these versions, please add the following dynamic configuration to enable stream-based replication:

```yaml
history.enableReplicationStream:
- value: true
```

Enabling this configuration will require a restart of your history pods.

#### Alternative Commands for Versions 1.28.1 and Prior
Version 1.28.1 and older do not provide the details necessary for setting up migration. If you are running an older version of Temporal, then substitute the below
The `temporal` command is missing some details needed for migration when run against Version 1.28.1 or older. If you are running that version of Temporal or older, then substitute the below
commands for the "temporal operator cluster describe" command cited in this document.

If you are using tctl, then substitute the following command: `tctl --address <frontend:7233> admin cluster describe`
