Cause

The target vCenter Appliance lacks sufficient space on the /storage/seat partition to accommodate all upgrade data.

Resolution

Option 1:
Initiate the Migration again. In stage 1, choose the next higher deployment size of the appliance VM.

Option 2:
Complete Stage 1 of upgrade. Power off the deployed vCenter/ Add an additional 50GB space to 'hard disk 8' viz. /storage/seat partition from the ESXi host client.
Take a snapshot of this vcenter appliance.
Open the temporary IP on port 5480 on a browser to complete the rest of the upgrade.(https://temporary_ip:5480)

Option 3:
Truncate the large tables identified in the source vCenter's database, and then rerun the migration process.
Determining where growth is occurring in the vCenter Server database
