We move your data to sovereign, open-source tools

Switching tools is scary: the real fear is losing emails, files, time. At Resurgamus we take the migration end to end, so you lose neither a byte nor a day.

We move you out of the Microsoft and Google ecosystems onto open-source solutions hosted in France: on-premise at your office or on a sovereign cloud. Your data is yours again.

And we do not vanish once the switch is done: we stay on as your managed IT, train your teams, and pick up when you call.

Any data, any infrastructure

Emails, files, databases, accounting, ERP, CRM, line-of-business apps: whatever the data, we migrate it. And whatever your starting infrastructure (any provider, public cloud, on-site server, Windows, Linux or Mac), we move you to sovereign, open-source systems, with no loss.

Mailbox migration

From Outlook, Gmail, IONOS or any provider, we move your email to Resurgamus hosting, to your own office, or to an independent cloud outside Microsoft and Google. No downtime, no loss, full history kept.

Case-file migration for law firms

We pull your case files out of legal software (SECIB, Lexis Nexis…), out of Excel or CSV files, or out of the cloud, and set them up cleanly in Optimus or Nextcloud. Confidentiality and compliance respected at every step.

Guidance and managed IT

We do not stop at the technical work: we onboard your teams, provide continuous support, and work directly with the Optimus team to evolve the software around your real needs.
