The migration, handled.

Downloading free software isn't the job. Running it in production is. That's the part we do.

Data migration

Export everything from Slack, transform, and import cleanly into Mattermost / Rocket.Chat. Nothing lost.

Parallel running

Old system stays live while the new one takes shape. Cutover only when you're ready.

Integration & SSO

Wire it into your existing email, auth, and payment stack. No isolated island.

Hardening & backups

POPIA-ready config, automated backups, monitoring, and patch management from day one.

Team training

Hands-on onboarding until your people are comfortable. Not a PDF they won't read.

Ongoing support

SLA-backed maintenance so you're not Googling error messages at 2am.

Three weeks from now, you could already have switched.

The audit is free. We'll give you a fixed-price migration quote, a timeline, and the risks, in writing. You decide from there.
