Legacy Web Application Modernization
PHP 5 to PHP 8, Python 2 to 3, Drupal 7 or Magento 1 to current versions: your old web application upgraded step by step, each step tested on a separate platform. No rewrite.
Every month on an unsupported version adds risk: flaws that will never be patched, a hosting provider that drops the old runtime, developers who refuse to touch it. And the big-bang rewrite you were quoted would freeze the business for a year.
There is a third way. We upgrade the stack you already have, in place, one controlled step at a time, until it runs on current, supported versions.
Step by Step, Never a Big Bang
- Inventory: runtime, framework, CMS, extensions, database, operating system, and what blocks each upgrade
- Plan: the order of the steps, each small enough to roll back
- Each step on a separate platform first: a copy of production, where your team and ours test the application before anything changes for your users
- Switch at the time you choose, with the previous version kept ready to come back
- Next step, only once the last one has run clean in production
What We Upgrade
- Language runtime: PHP 5 to 8, Python 2 to 3
- Frameworks and CMS: Drupal 7, Magento 1, Joomla 3, PrestaShop 1.6, old WordPress and their extensions
- Database engines and their versions
- The operating system underneath, through a DevOps mission
Why It Works
We have kept stacks running for 15 years by upgrading them in place, one controlled step at a time. Until the last step, your platform stays under our Legacy Web Application Maintenance: secure and online the whole way.
Pricing
A project, scoped and priced after the inventory. You know the plan and the price of each step before it starts.
