    Hi raj_raut​ qq, may I ask whether you reactivated the license prior to performing the upgrade?

    If not, I would recommend you reactivate the license and take a reboot of the instance. You might be facing this issue due to Service Date Problem. 

     

    If the service check date is missing or is earlier than the license check date, the system will fail to load the configuration when you attempt to boot the upgraded software. If you boot into your newly upgraded system and the configuration fails to load due to a service check date issue, you can resolve this by reactivating your license.

     

    Also, I agree with LiefZimmerman​ , that you should contact Support for assistance in such situations. That said, the DevCentral Community is always available to help with any questions or clarifications you may have. I hope your issue has already been resolved by now.

     

    Hope it helps!

raj_raut​ - your post was held in moderation for a while. Your best bet is still probably connecting with Support.
If you have a ticket already that's good, but if you are still waiting to hear back you may find some guidance here on DevCentral (which may also help clarify a few basic questions for Support and result in a quicker resolution)
