About this gig

Your application runs on an old PHP or .NET version and you want it on a supported version, without breaking anything for your users.


I have migrated my own products between stacks several times: an ASP.NET MVC application to Laravel and on to ASP.NET Core, and a .NET web shop and SaaS to Laravel, each time with the same URLs, texts and behaviour for visitors.


How I work:

  • first a scan and a written plan: what changes, what can break, and how we test it
  • the upgrade on a copy or staging environment, with feature tests where possible
  • a check that URLs, forms, payments and emails still work
  • a written handover and help with going live

Start with the Upgrade plan if you are not sure how big the job is.
