Steve, You will have to install the 6.2.3 first on your 64 bits system and then restore DB. Then , upgrade to 6.3.1. Please make sure you save a copy of volume history file for 6.2.3. We changed format of the volume history file with 6.3. The volume history file in 6.3 can not be used to restore DB into 6.2 or 6.1.
