When a new version of a SendSafely connector template is released — or you need to apply a configuration change — you update your existing CloudFormation stack rather than deleting and redeploying it. Updating in place preserves the stack's identity, its outputs, and any resources that don't need to change.

This article uses a change set, which lets you preview exactly which resources will be added, modified, or removed before anything is applied. This is the recommended approach for production stacks.

Note: Creating a change set does not modify your stack. Nothing changes until you explicitly execute it, and you can delete a change set at any time without affecting the running stack.

Before beginning the update process please contact your account representative or Support for an update CloudFormation template(YAML file).

Step 1 — Open the stack

1. Sign in to the AWS Management Console and open the CloudFormation service.
2. Confirm you are in the correct region (top-right of the console).
3. In the left menu choose Stacks, then select the stack you want to update.

Step 2 — Start a change set

1. With the stack open, choose Update stack → Create a change set.

   

2. Then for Change set type select "Standard change set" and for Prerequisite - Prepare template select "Replace existing template"

    

3. For Specify template select "Upload a template file" and upload the YAML file provided by SendSafely and press Next.
    
4. On Specify change set details page Change set name should be automatically populated. You can provide a change set description if you would like as it is an optional field. You can change entries in the Parameters if you would like or leave it as it is and press Next.

5. On the Configure change set options - optional page, leave everything as it is and scroll all the way at the bottom of the page and select all the options under Capabilities and transforms. Then press Next.

   

6. On the Review change set page scroll all the way to the bottom and press Create Change set.
7. This should take you to a new screen where the change sets will be created. Monitor the change set and wait for it to be completed. Once the change set creation is complete you can select "Execute change set" which should update the stack resources with new updates.
