Moving one WordPress site is easy. Moving twenty in a weekend is a pipeline, and the failures that cost you are the quiet ones: writes landing on the old server, cron firing on two boxes, certificates blocked by ACME rate limits. Here is the fleet migration process I use, from manifest to per-site rollback.
Choosing between Lightsail, EC2 and ECS for a small client workload is not a performance question. It is a question about which constraints you are accepting and how expensive they are to reverse. Profiles of all three with where each wins and loses, the cost levers that actually move the bill, a six-step decision procedure, and the arguments that fall apart on contact with a real project.
Managed WordPress hosting and a self-managed VPS can both serve a fast site. They differ on which failures land on you. A practical comparison covering visit metering, disallowed plugin policies, silent backup failure, patching debt, and a cost model that survives contact with reality.
Moving a WordPress website involves much more than copying files. This practical migration guide explains how to transfer WordPress safely, minimize downtime, protect SEO, preserve email services, and avoid lost data.
