Customer Scenario

A customer has a Chef Server 12 (HA - DRBD) in Production. They want to test an in-place upgrade (or maintenance) using their current OPC Production data and config. This gives us a good chance to make corrections if we find that their data is too broken for the migrations to handle, and gives the customer experience in managing the upgrade in Production.

The sequence of events will broadly be these:

• Install the same version of Chef Server on the target HA Test cluster
• Restore data from Production instance backup (LVM snapshot or full-stop backup)
• Test
