I'm not sure what you mean here. In order to upgrade to mSecure 6, you simply download the new app from the either of the links below:
• iOS: https://itunes.apple.com/us/app/msecure-password-manager-and-secure-wallet/id1063795594
• Android: https://play.google.com/store/apps/details?id=com.mseven.barolo
• Mac: https://itunes.apple.com/us/app/msecure-password-manager-and-secure-wallet/id1157750250
• Windows 10: https://www.microsoft.com/en-us/store/p/msecure-5/9nblggh62pc8
The new version will download over the top of mSecure 5, and you'll see your data in the new app. Have you downloaded mSecure 6 onto your various devices? If you did, what happened?
