Once upgraded, perform `systemctl restart minio` across all nodes in **parallel**. RPM/DEB based installations are usually automated using [`ansible`](https://github.com/minio/ansible-minio). +- For installations using Systemd MinIO service, upgrade via RPM/DEB packages **parallelly** on all servers or replace the binary lets say `/opt/bin/minio` on all nodes, apply executable permissions `chmod +x /opt/bin/minio`. Proceed to perform `systemctl restart minio` across all nodes in **parallel**. ### Upgrade Checklist - Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk. - Read the release notes for the targeted MinIO release *before* performing any installation, there is no forced requirement to upgrade to latest releases every week. If it has a bug fix you are looking for then yes, else avoid actively upgrading a running production system. -- Make sure MinIO process has write access to `/opt/bin` if you plan to use `mc admin update`. This is needed for MinIO to download the latest binary from and save it locally for upgrades. +- If you plan to use `mc admin update`, MinIO process must have write access to the parent directory to provide in-place upgrades. - `mc admin update` is not supported in kubernetes/container environments, container environments provide their own mechanisms for container updates. - **We do not recommend upgrading one MinIO server at a time, the product is designed to support parallel upgrades please follow our recommended guidelines.**
