How to Upgrade NBU from 6.5.4 to 7.6.0.1

[mfire]

• Customer environment is hp-ia 11.23,cannot support 7.6.0.1,so must first upgrade the operating system to 11.31.
• So step is
• 1.6.5.0.4 catalog backup
• 2.hp11.23 upgrade to 11.31
• 3.reinstall 6.5
• 4.reinstall 6.5.0.4
• 5.restore catalog to new 6.5.0.4
•  
• So my question is upgrade straight to 7.6.0.1 or first upgrade to 7.1/7.5?
•
