**Mattermost v10 is almost upon us and this significant milestone is much more than just a version.** Our engineers have been working for many years on performance and scale, ensuring that your Mission Critical collaboration works no matter the number of users, teams, channels or DM/GMs. In Mattermost v10 we have now reached support for 100k concurrent users! One key area in achieving this scale is our focus on PostgreSQL, so much so that over a year ago we took the decision to deprecate support for MySQL by Mattermost v11 (coming late 2025). To support MySQL users transition to PostgreSQL [we created a guide to help](https://docs.mattermost.com/deploy/manual-postgres-migration.html). We then took this a stage further a built a tool to do this work for you. The tool [`migration-assist`](https://docs.mattermost.com/deploy/postgres-migration-assist-tool.html) automates connections and the migration of data. The guides/tools for all deployments from the smallest up to the very largest. We are continually updating migration-assist so all feedback is welcomed. As mentioned support for MySQL will end with Mattermost v11 but now is a good time to make the move to PostgreSQL as you consider your v10 upgrade. You can join the conversation over at [Mattermost](https://community.mattermost.com/core/channels/transition-to-postgresql) (where our engineers are also on hand to lend a hand).
