// The Context

Where it started

This banking institution still relied on an aging on-premises infrastructure, costly to maintain and difficult to scale to absorb the growth of its digital activity.

Every new feature required significant deployment time, and the internal technical team spent a growing share of its time on corrective maintenance rather than innovation.

Beyond technical performance, any change had to remain strictly compliant with the financial sector's regulatory requirements, ruling out any improvised approach.

// Our Approach

What we put in place

We began with a complete audit of the existing infrastructure, to identify components that could migrate as-is, those requiring adaptation, and compliance risks to anticipate before any transfer.

The migration was then planned in batches, with cutover windows chosen outside peak hours, each step validated through regression testing before moving to the next.
