Ref Arch - can we use existing AWS accounts and organizations?
A customer asked: > I am preparing for a Gruntwork Reference Architecture deployment. Here is my current account layout at my company. Can we use any of the existing accounts we already have?
Gruntwork requires _**brand new, never-before-used AWS accounts**_. Even if you have a simple baseline applied to your accounts, they can conflict with the Reference Architecture, which will severely delay delivery of your deployment. It is fine to use an existing AWS organization, so long as you create brand new accounts under that org. Note! You can use [the Gruntwork CLI](https://github.com/gruntwork-io/gruntwork) to do all the heavy lifting for you when you are preparing for a Gruntwork Reference Architecture deployment. This tool can: * Create new accounts for you underneath your target org (it will make zero changes to your Organization) * Optionally register domain names for you * Grant Gruntwork engineers temporary access to your new accounts so they can deploy your Ref Arch * Programmatically request AWS API quota / limit increases to reduce the likelihood of your deployment getting held up due to the new account limits / protections put in place by AWS. **It is strongly recommended that your use the Gruntwork CLI to prepare for your Ref Arch deployment!**
