Replacing a Computer

To replace a computer you have backed up with McAfee Online Backup, you should begin by moving, downloading, or restoring all your previously backed up files to the replacement computer.
When the new computer has the same platform as the computer being replaced (both use Windows or both use Mac), you can install the McAfee Online Backup backup software using your same McAfee Online Backup account credentials to associate your files already in the McAfee cloud with the new computer, as if they had always been backed up from the new computer.
CAUTION:
Doing this does not automatically put your previously backed up files onto the replacement computer!

When the new computer and the computer being replaced have different platforms (one is Windows and the other is Mac), the backup software cannot associate your files already in the McAfee cloud with the new computer. In this situation, first ensure all your previously backed up files are present on the new computer. Then, install the backup software on the new computer, using your same McAfee Online Backup account credentials. Once your files are backed up from the new computer, delete the old computer from your account. If you have backed up the maximum number of computers allowed by your account, you cannot install the McAfee Online Backup backup software on the new computer until you delete the replaced computer from your account.
