What are the consideration when Downgrading from from Unlimited to Enterprise edition?Can you please provide your insights if you did a downgrade between instances? Has anyone done this type of downgrade? Is it hard and are there complications or is it just as simple as flipping a switch?
I suggest you review Salesforce Features and Edition Limits. The Unlimited Edition allows MANY more Validation Rules/object, custom fields/object, custom objects, includes free support, unlimited on-line training, has many more sandboxes, an unlimited number of custom applications (vs a maximum of 10) and much more. See How to select the right Sales Cloud edition for more specifics and additional details that I've not covered as there's a huge difference between the two and much you'll need to check for if you're going to downgrade.
