Azure Database for MySQL flexible servers on MySQL 5.7 (paid extended support since October 1, 2026) or 8.0 (paid extended support from February 1, 2027)

What LeftSize checks

Azure Database for MySQL Flexible Server 5.7 left Azure standard support on September 30, 2026. Servers still on 5.7 were automatically enrolled in Extended Support on October 1, 2026 and are charged per vCore per hour. MySQL 8.0 follows: standard support ends January 31, 2027, Extended Support (billed) starts February 1, 2027.

Why it matters

Missed retirement and end-of-support dates turn into forced upgrades, outages or extended support charges at a moment you did not choose.
