Hi caulfiedd@live.cn<CAULFIEDD>,

If you are upgrading from 12.1X to later versions you can go for ISSU, it works smoothly . If you are not in 12.1X series then the best method is minimal downtime method as explained in following URL http://kb.juniper.net/InfoCenter/index?page=content&id=KB17947

Regarding ISSU, below URL provides the commands,working,limitations rolling back etc
