Portainer releases contain new features and bug fixes so it's important to keep your installation up to date. We have tested and validated all Portainer version upgrades from 2.0.0 up to the latest release.
While it's possible that an untested unvalidated update path might work, we recommend that all update paths are tested and validated on a non-critical system before applying them to your production systems.
Starting with CE 2.9 and BE 2.10 Portainer is HTTPS enabled by default and uses port
9443to serve the UI. HTTP can still be enabled on port
In general, we recommend updating your Portainer Server deployment before you update the Portainer Agents. When we release new versions of Portainer we ensure that Portainer Server is able to talk to older versions of the Agent, and in most cases the reverse is true, but in some instances we make changes to the Agent that are not fully backward compatible with older versions of Portainer Server.
From 2.19, Business Edition users are able to update their Portainer installation directly from within Portainer. To do so, click the Update now link in the update notification in the bottom left of the Portainer UI.
In the confirmation dialog, click Start update to proceed with the update.

If you are coming from Portainer CE or the 1.24.x branch, we have guides for you as well.
