Migration from Spring Cloud AWS 2.x to 3.x

[Levi245532]

Hi everyone,

I am planning to migrate from Spring Cloud AWS 2.1.x to 3.4.
In doing so, I’m wondering how to modify the following existing properties for 3.x:

cloud.aws.region.auto=true
cloud.aws.stack.auto=false

I’ve checked the docs, but there are no direct mentions regarding the above settings.
Migration from 2.x to 3.x

Additionally,
the settings list (Appendix A: Common application properties) does not seem to include configuration items matching these settings.

Question:
cloud.aws.region.auto=true
Based on the reference,
I think that in 3.x, the default auto-configuration provides behavior equivalent to auto. So, if there are no environment changes, is it correct to assume that no specific settings are required?

cloud.aws.stack.auto=false
This configuration in version 2.x was defined to prevent AmazonServiceException(AWS SDK 1.x) from occurring and causing the application to fail to start if an AWS CloudFormation stack could not be found.
In 3.x, does the absence of this setting result in errors, or should additional configurations be made?

Since I cannot immediately verify this in the actual environment,
I would greatly appreciate help from anyone knowledgeable about this matter.

Hi @Levi245532!

By default region is automatically resolved through AWS SDK (see docs)

In 3.x we dropped support for CloudFormation stacks, so you don't need to do anything to have an equivalent of cloud.aws.stack.auto=false.

We are aware of poor migration guide from our side so feel free to post more questions if you have any.
