**Q. Will there be future updates to Single Server to support the latest PostgreSQL versions?**
9190

9291
**A.** We recommend you migrate to Flexible Server if you must run on the latest PostgreSQL engine versions. We continue to deploy minor versions released by the community for Postgres version 11 until it's retired by the community in Nov'2023.

> We're extending support for Postgres version 11 past the community retirement date and will support PostgreSQL version 11 on both [Single Server](https://azure.microsoft.com/updates/singlepg11-retirement/) and [Flexible Server](https://azure.microsoft.com/updates/flexpg11-retirement/) to ease this transition. Consider migrating to Flexible Server to use the benefits of the latest Postgres engine versions.

**Q. How does the Flexible Server 99.99% availability SLA differ from Single Server?**
9896

9997
**A.** Flexible Server zone-redundant deployment provides 99.99% availability with zonal-level resiliency, and Single Server delivers 99.99% availability but without zonal resiliency. Flexible Server High Availability (HA) architecture deploys a hot standby server with redundant compute and storage (with each site's data stored in 3x copies). A Single Server HA architecture doesn't have a passive hot standby to help recover from zonal failures. Flexible Server HA architecture reduces downtime during unplanned outages and planned maintenance.

**Q. I have a private link configured for my single server, and this feature is not currently supported in Flexible Server. How do I migrate?**
113110

**A.** Flexible Server support for private-link is our highest priority and on the roadmap. This feature is planned to launch in Q4 2023. Another option is to consider migrating to VNET injected flexible server.
