Q: forgot my old apple id password and cant restore

If its only on the device that you are trying to use the new appleid,  All you have to do is delete the old appleid and put the new one in then your password.  You shouldn't get a message asking you to enter old password.

Try this.

If you're asked for the password to your previous Apple ID when signing out of iCloud

Change your Apple ID temporarily

If signing out and back in to iMessage or FaceTime didn't help, try these steps:

1. Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.
2. Tap Settings > iCloud. Complete these steps only if the Find My [Device] setting is turned on:
   1. Scroll down and tap Sign Out, then tap Sign Out to confirm. If you're using iOS 7 or earlier, tap Delete Account, then tap Delete to confirm.
   2. Tap Keep on My [Device] or Delete from My [Device]. In either case, your data remains in iCloud and will be updated on your device when you sign in to iCloud again.
   3. Enter the password for your previous Apple ID.

Did you select Delete from My [Device]?

If you're still asked for your previous Apple ID password, continue to the next step.

Update to the latest version of iOS

Update to the latest version of iOS on your iPhone, iPad, or iPod touch, then try signing out of iCloud again.
