- If you must run 2.5.1, consider air-gapping the system or using it only in an isolated lab.
- Upgrading from 2.5.1: You can upgrade directly to a supported version (e.g., 2.6.0, then to 2.7.x) using the built-in System > Update page — provided the package repository for 2.5.1 is still partially functional (though some mirrors may be deprecated).
