>We've used Appengine for 12 years now, and every time they've decided to deprecate services, there's always plenty of notice, a superior replacement, and usually lower costs.

That doesn't remove the cost and time of updating your code and migrating.

100% this. Deprecating things your customers use always sucks for your customers. No matter what. It doesn't matter how long the notice is. It doesn't matter how good the replacement is. You have made work for your customers that they wouldn't otherwise need to do.

In most? cases it should make up for that in lowered cost savings moving forward.

That should be a decision for the customer to make and not one that is forced on them. Many larger companies tend to have legacy systems that are basically black boxes to them. The cost of updating one can be orders of magnitude more than any cloud costs for running it.
