I was running 7063-CR2s with V11R1 code and using the GUI. I utilized the blue box HMC Action to "Upgrade HMC".
First, I selected to save the HMC Upgrade data to the HMC itself.
Second, I choose to download from the IBM Website. I selected MF71772 version of V11R2 for "7063-CR2 ** ONLY **". It was the only option presented.
Third, the summary was presented and I proceeded with the upgrade.
The fourth Upgrade HMC panel shows that the upgrade data was saved, the download file was verified and then the upgrade began and it logged me out of the GUI.

After 38 minutes the HMC started responded to the pings to the public IP but it would not respond to attempt to login in to the GUI or directly through a PuTTY session.
When I arrived onsite and viewed the console, it appeared normal and allowed me to log in with my user and previously password with no issue.
When viewing the HMC Management >> Network Configuration screen, the firewall settings on the public ethernet connections were reset. SSH/22 and Web/443 were do not allow. NTP/123 was still allow by IP but the IPs were 0.0.0.0.
When viewing the Schedule Management, it was blank. My Backup Profile data on each frame and Backup HMC data were deleted.
I had to manually reenter all of these items. Once completed, I brought the HMC down hard (pulled power cords), brought it back up and the entries were all still there. I then HMC Action >> Backup HMC Data of up the new V11R2 data to USB.
I anticipate that a new SP will be released once they determine if the issue is that it fails to save the data or fails to restore the data.

Update - Support acknowledges that there is a bug in the V11R1 to V11R2 upgrade. I performed it on two different HMCs using the GUI and accessing the code from the IBM Website.
<< From my case >>
Apologies- did forgot to send you a follow up mail that is being reviewed. Indeed at the moment it seems that the save upgrade data did not restore fully/ correctly.
But case and data is also being reviewed by a Product Engineer still.
