# Upgrading
Upgrades between minor versions of the agent, like from 1.1 to 1.2 are always backwards compatible. Upgrades that involve a major version bump often come with some backwards incompatible changes.
Before upgrading the agent, be sure to review the:
- [Agent release notes](https://www.elastic.co/elastic/docs-builder/docs/3410/release-notes/apm/agents/dotnet)
- [Agent and Server compatibility chart](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/3410/solutions/observability/apm/apm-agent-compatibility)


## End of life dates

We love all our products, but sometimes we must say goodbye to a release so that we can continue moving forward on future development and innovation. Our [End of life policy](https://www.elastic.co/support/eol) defines how long a given release is considered supported, as well as how long a release is considered still in active development or maintenance.
