I want to degrade ASR IOS from asr1000rp2-advipservicesk9.03.04.02.S.151-3.S2.bin to asr1000rp2-advipservicesk9.02.04.02.122-33.XND2.Its a non production router.While I am doing ISSU steps I am getting below error.

What is the easy step to degrade the IOS.Since its a non production router thre is no issue of downtime.
New IOS : asr1000rp2-advipservicesk9.02.04.02.122-33.XND2
