summary
Claims a one‑person migration of 400 directories to OpenTofu completed in a single day, with preparatory test runs and updated automation scripts. Uses S3 backends and a custom drift‑detection script that takes about 2 hours to run, runs parallel open‑tofu plan and apply across state files, and upgrades through 1.62 then 1.90. Process takes roughly 7–8 hours, results in clean drift checks and a quick follow‑up to adopt Terara Team for PR workflows.
