Thanks...but this will not solve my prob.
I have access to my blockchain.info wallet so no need to restore it.
I imported the address that holds the bitcoin but I can not see the private key I need to transfer that 1 btc to my wallet...
Ow looks like your bitcoin is in your old blockchain wallet and now blockchain upgraded into HD wallet this is the reason why you don't get your bitcoin from your old account..
I found post from reddit same issue like yours that someone posted that he got wallet.aes.json and recover it using multibit older version..
Exactly the same thing happened me. Old wallet from 2013 I hadn't tried to get coins out of in years. I went through support many times and had no way of getting my coins out. No way to change or remove my 2nd password either. If I tried to send them, after entering 2nd password I got send failed:
https://i.imgur.com/pBk8fJc.png (and if I entered a different password, I got incorrect password, so I knew the 2nd password was correct.) Does yours say send failed or incorrect password if you try to send coins out?
The seed idea (HD Wallets) wasn't there in 2013 though. My coins were still in the older style of wallet, and I couldn't move them to the newer one (or anywhere). The blockchain.info page was showing two types of wallet for me. I don't have it open in front of me now, but one in a section called "My Bitcoin Wallet", this is the newer HD one with a seed, but my coins were all in the older one under something like "Imported Addresses". Are your coins definitely in the type of wallet which has a seed? ("My Bitcoin Wallet") Mine weren't. If they're in the Imported Addresses section, the HD seed won't help you. (You say you're being asked to upgrade account, which makes me think your coins are in the older style.)
Do you have an old backup of your wallet? This was the only way I could finally get my coins. I luckily had an old backup in my email. (filename wallet.aes.json), and I was able to import that into an old version of Multibit (you need 0.5.17 for this, newer versions removed support for the old blockchain.info wallet backup format). This asked me also for my 2nd password, and thankfully this worked. (Support were also able to send me an old backup, but it was my own backup which I used.)
There should be a PSA done here for anyone who has left coins in a blockchain.info wallet since 2013 to try to get them out, as I imagine many others can see their wallet but don't know they'll have a lot of trouble trying to get them out.
