Hi Manish,
I don't see any answers yet from ADA but I think I found the one you might need.
According to this Upgrade Paths page from the CA ADA Wiki Docs:
Upgrade Paths - CA Application Delivery Analysis - 11.0 - CA Technologies Documentation
"You can upgrade CA Application Delivery Analysis from version 10.2, 10.3, 10.4, 10.5, or 10.6 to version 11.0."
It might be the case that you'll need to go from 10.0 to 10.2 before going to 11.0.
To receive a more precise answer to that question at this time I'd recommend a support case be opened with the CA ADA Support Team for more information.
Hopefully that at least closes the loop on this forum thread and answers the questions posed here.
Thanks,
Michael
