Cloudformation append to stack

I have an AWS stack with lambda and api gateway resources. There are about 250 resources and cloudformation only allows uploading 200 at a time so I split it into 2 templates. However when I run the deploy commands for each stack like so

aws cloudformation deploy --template-file template.yml --stack-name my-stack --region us-east-1 --capabilities CAPABILITY_IAM

aws cloudformation deploy --template-file template2.yml --stack-name my-stack --region us-east-1 --capabilities CAPABILITY_IAM

the second command deletes what the first command deployed to my-stack. I would like to append the resources in template2.yml to my-stack and keep what was deployed from template.yml. Is there a way to do that? I want the resources in both templates to use the same api gateway endpoint.

You could deploy this specifications into two different stacks (diferent stack names), besides you could reference the api gateway specification from the first stack into the second stack, this is one way to reference lambda functions in same api gateway.

They are technically 2 stacks, but you only gave 1 stack name. So the later command will overwrite the deployed my-stack based on template.yml.

Change your 2nd command to use a different stack name like my-stack2
