Q: Old Apple ID

What service(s) is asking for the old Apple ID password? If it's an app update you need to delete the app and buy it again with the new Apple ID. If not then read on for some settings that I'd check.

Settings > iCloud > (Scroll Down) Delete Account > Sign in with the new Apple ID -- Note: This only affects the device

Settings > iTunes & App Store > Apple ID > Sign Out > Sign in with the new Apple ID

Settings > Messages > Send and Received > Apple ID > Sign Out > Sign in with the new Apple ID

Settings > FaceTime > Apple ID > Sign Out > Sign in with the new Apple ID

These are the basics. For a full list read here > What to do after you change your Apple ID email address or password - Apple Support

If you forgot the Apple ID Password try the steps here:

Why do you think the Apple ID does not exist anymore?

Apple IDs are not deleted. The problem you are experiencing is that Find my iPhone is active with the old ID and the only way to turn it off is to use the PW associated with that ID. Try to recover the PW by following the steps in the link I provided.

That's a tricky one that will require you to posses the email address use to turn on find my iPhone. I hope you didn't deactive it with the email provider.

Go here > https://appleid.apple.com/ Change the email address for your Apple ID back to the one used for Find my iPhone and wait 10 minutes for iCloud realize the change.

Onthe device go Settings > iCloud > Find my iPhone > Toggle off. If you get an error try again in a few minute.

Once Find my iPhone is off return to https://appleid.apple.com/ and change the email back to the one you are currently using.

I also no longer have that email so I can not recover and email for the ID.

I was typing when you posted this. Sorry friend without the email account there is no way around your situation.

My suggestion to you is to contact Apple ID Support here:  Contact Apple for help with Apple ID account security - Apple Support

There are other ways besides your email to recover an ID, for instance security questions. If you have none, your only option is to take the device to an Apple Store with proof of purchase.

I second what elcpu just posted.
