Spring Security 6.0 Migration Guide
This document is meant to help you migrate your application to Spring Security 6.0.
If you are using Spring Boot, consider reading the Spring Boot 3.0 Migration Guide.
Before you start the upgrade, make sure to upgrade to the latest available 5.8.x version. This will make sure that you are building against the most recent dependencies of that line.
The 5.8.x is a special release that was designed to help you to migrate to Spring Security 6.0. Spring Boot 2.7.x, the latest release in the 2.x line, does not use Spring Security 5.8.x, because of that, you have to override the dependency versions manually.
There are several deprecations that were removed in 6.0 that should be replaced in 5.8.x. To help with that, you can read the Prepare for 6.0 section of the documentation and apply the suggested changes.
After you upgraded to 5.8.x and all the necessary changes were applied to your application by following the Prepare for 6.0 documentation, you are now ready to upgrade to 6.0.
If you are using Spring Boot, you should upgrade it to 3.0. Otherwise, you can follow the instructions here.
After upgrading the dependency versions, please refer to Migrating to 6.0 to perform any remaining migration or cleanup steps.
