This may be a little late, but I've recently successfully upgraded a pair of C6513-E VSS switches with quad 2T-SUPs using the steps below. Hope this information can help someone out in the future!
Step1: Copy the image over to the core switch via TFTP
copy tftp: bootdisk:
Address or name of remote host ? <IP of TFTP server>
Source filename ? s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
Destination filename [s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin]?
Step2: Check the image in bootdisk:
Step3: Verify the md5 checksum for the image in bootdisk:
verify /md5 bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
Step4: The 2T-SUPs are in slots 7 and 8 on both switches. Check to make sure that slot 7 of switch 1 already has the image (by default, copying the image to bootdisk will automatically generate the image in sw1-slot7-bootdisk)
Step5: Copy the IOS image from the active SUP to the other 3 SUPs.
copy sw1-slot7-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin sw1-slot8-bootdisk:
copy sw1-slot7-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin sw2-slot7-bootdisk:
copy sw1-slot7-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin sw2-slot8-bootdisk:
Step6: Verify that the image is present on the both the active and standby switches.
Step7: Verify that the image is good on all the SUPs.
verify /md5 sw1-slot7-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
verify /md5 sw1-slot8-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
verify /md5 sw2-slot7-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
verify /md5 sw2-slot8-bootdisk:s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
Step8: Set the boot variable. Keep the old image as backup in case the new image fails.
no boot system flash
boot system flash bootdisk:/s2t54-advipservicesk9-mz.SPA.151-2.SY12.bin
boot system flash bootdisk:/s2t54-advipservicesk9-mz.SPA.151-2.SY7.bin
Step9: Check the boot variable for all SUPs on both the active and standby switches.
remote command switch-id 1 module 7 show bootvar
remote command switch-id 1 module 8 show bootvar
remote command switch-id 2 module 7 show bootvar
remote command switch-id 2 module 8 show bootvar
Step 10: Check to make sure the configuration register is set to 0x2102.
show version | i x2102
Step11: Reload the standby switch.
redundancy reload peer
Step12: Once the peer comes into RPR mode (show redundancy), reload the active switch.

I ran into a scenario where two C3850 switches formed a stack, despite having different IOS versions. I'm curious as to why this happened. Has anyone experienced anything like it before?
