- **Forced**: This option is designed for rapid recovery in scenarios such as regional outages. Instead of waiting to synchronize all the data from the primary, the server becomes operational once it processes WAL files needed to achieve the nearest consistent state. If you promote the replica using this option, the lag at the time you delink the replica from the primary indicates how much data is lost.

> The **Forced** option skips all the checks, for instance, the server symmetry requirement, and proceeds with promotion because it is designed for unexpected scenarios. If you use the "Forced" option without fulfilling the requirements for read replica specified in this documentation, you might experience issues such as broken replication. It is crucial to understand that this option prioritizes immediate availability over data consistency and should be used with caution.

> The **Forced** promotion option is specifically designed to address regional outages and, in such cases, it skips all checks - including the server symmetry requirement - and proceeds with promotion. This is because it prioritizes immediate server availability to handle disaster scenarios. However, using the Forced option outside of region down scenarios is not allowed if the requirements for read replicas specified in the documentation, especially server symmetry requirement, are not met, as it could lead to issues such as broken replication.

- [In-place major version upgrade](concepts-major-version-upgrade.md) in Azure Database for PostgreSQL flexible server requires removing any read replicas currently enabled on the server. Once the replicas have been deleted, the primary server can be upgraded to the desired major version. After the upgrade is complete, you can recreate the replicas to resume the replication process.

- **Storage auto-grow**: When configuring read replicas for an Azure Database for PostgreSQL flexible server instance, it's essential to ensure that the storage autogrow setting on the replicas matches that of the primary server. The storage autogrow feature allows the database storage to increase automatically to prevent running out of space, which could lead to database outages. To maintain consistency and avoid potential replication issues, if the primary server has storage autogrow disabled, the read replicas must also have storage autogrow disabled. Conversely, if storage autogrow is enabled on the primary server, then any read replica that is created must have storage autogrow enabled from the outset. This synchronization of storage autogrow settings ensures the replication process isn't disrupted by differing storage behaviors between the primary server and its replicas.

- **Premium SSD v2**: As of the current release, if the primary server uses Premium SSD v2 for storage, the creation of read replicas isn't supported.

- **Reseting admin password**: Resetting the admin password on the replica server is currently not supported. Additionally, updating the admin password along with [promoting](concepts-read-replicas-promote.md) replica operation in the same request is also not supported. If you wish to do this you must first promote the replica server and then update the password on the newly promoted server separately.
