I was on the phone with Apple today. After resetting the TC and erasing the HD and reinstalling the OS again, the Apple folks had me do the migraton assistant again. This time I was taliking with a TC support person. When it came time in the process to recognize and select the MacBook Pro data on the TC, he had me wait about 30 seconds. And sure enough after that time both the TC data for my iMac AND for my MacBook Pro were displayed and I could select the correct one. My previous mistake was going with the first selection and not giving TC enough time to display both back ups.
So after the 30 second wait and selecting the correct Back Up, everything went perfectly.
Thanks for listening and I hope this helps someone out there!
