Guideline to upgrade from 3.1 to 4.6 with HW upgrade at the same time

1. Do a system copy of the 3.1 instance to the new box.

2. Bring up 3.1 instance in new box.

3. Upgrade the Development/Staging instance and resolve all errors and issues. Create SPAU/SPDD modifications, if any.

4. Timing the upgrade processes - to determine how long the whole processes take.
Your managers will like to know how long it takes to complete the upgrade.

5. Do a system copy of the 3.1 instance to the new box again

6. Bring up 3.1 instance in new box.

7. Make the 3.1 instance in new box as the Production instance.

8. Make the 3.1 instance in the old box as the Development/Staging instance or a standby Production Box in case the upgrade fail.

9. Upgrade the Production instance as planned (i.e. 3 full working days).

10. Acceptance testing.
