Quite possible that the new MSM have old EXOS than the MSM-B, and thus both MSMs are experiencing sync issue.
Hi Harkanwalijeet,

Thanks for your reply,
when we execute sync from master it should copy current EXOS to new msm & will upgrade and both will sync and it will start work ?

Hi Pari,
It depends. If the version of code on the MSM is too old (Pre EXOS 12.6) it might not be able to sync and would have to be done manually.
