Modernizing software means replacing an aging system with a current, secure and maintained application, without losing its history. J3B Web studies the old system, carries over its data with import tools that can be rerun and checked, then prepares a short switchover with a rollback plan.
Software can run for years and turn into a risk without anyone noticing.
The developer has left, and every fix is a worry.
A version of PHP or of a framework that no longer gets security updates.
Taxes calculated separately, amounts rounded badly, categories in free text.
No phone version, no online payment, no two-factor authentication.
Its tables, its hidden rules and the data that no longer follows those rules.
Read-only access to the old database, a dry run, then the real import, as many times as needed.
Record counts and money totals are compared between the old and the new system.
Every record that doesn’t make it through is listed in a file, so a person can decide what to do with it.
A timed plan, with a rollback ready just in case.
Current versions of PHP and CodeIgniter, two-factor authentication and encrypted backups.
Step 11 to 2 weeks
J3B Web uses the old software with your team and reads its database, to spot the rules nobody wrote down.
Step 2About 1 week
The plan lists each table, what it becomes, and the modules to replace first.
Step 31 to 3 weeks
The new screens fix what frustrated people in the old ones, without throwing off regular users.
Step 44 to 16 weeks depending on scope
The imports run from the start of development, on a copy of your real data.
Step 51 to 2 weeks
The last import, a comparison of the counts and totals, the switchover according to plan, then training.
Step 6Ongoing
Regular security updates, so the new software doesn’t age like the old one.

Yes. At Agence Distinction, the migration tools carried over more than 4,000 clients and 13,000 invoices from the old system. Each import compares the counts and money totals between the old and the new system.
No. The switchover is prepared ahead of time and takes little time, with a rollback plan. Your team uses the old system until the last moment.
Not always. Depending on the system, one module can be replaced at a time, keeping the old one for the rest during the transition.
Software that no longer gets security updates exposes your data and your clients’ data. Under Law 25, an incident involving personal information may have to be reported to the Commission d’accès à l’information.

Plugins that connect a WordPress site to a ticketing system, an inventory or a CRM, and protect the editors’ changes.
