The Junos 21 branch is now in Junos recommended versions for MX routers, see https://kb.juniper.net/InfoCenter/index?page=content&id=KB21476&smlogin=true
Upgrading our MXs has several advantages:
- Testing routers redundancy in a planned window
- Keeping a tight Junos version spread (we currently have 12, 14, 15, 17, 18, 20)
- Leveraging features improvements (eg. DNS in mgmt-junos see T269340)
- Fixing low risk security issues
Process is documented in https://wikitech.wikimedia.org/wiki/Juniper_router_upgrade
