Terraform 0.14.x	✅ Compatible	Recommended minimum version
Terraform 0.15.x	✅ Compatible
Terraform 1.0.x	✅ Compatible	Current recommended version
Terraform 1.1-1.6	✅ Compatible	Latest stable versions
Terraform 1.7+	🟨 Likely compatible	Monitor release notes for breaking changes
Terraform 2.0	❓ Unknown	Major version will likely require updates

Provider Version Issues

1. AWS Provider Version ~> 1.0:

   • This is extremely outdated (current is 5.x)
   • Many resources and attributes have changed
   • Immediate recommendation: Update to at least 3.x or 4.x

2. Missing Explicit Provider Requirements:

   • Some files lack provider version constraints
   • Terraform 0.13+ requires explicit provider source and version constraints

Goal

1. Test with Terraform 1.0+ series:
   • Move to the latest 1.x version
   • Update AWS provider to at least 4.x
   • Run full test cycle
