When your e‑commerce site is the leading online parapharmacy in France, every minute of downtime stings. For Easypara, the pain became acute after its upgrade from Magento 1 to Magento 2: the legacy, self‑hosted infrastructure simply could not keep up, leading to frequent incidents and unacceptable outages.

What follows is the inside story told during our recent French‑language webinar of how Easypara, digital agency Dn’D and cloud platform provider Upsun (the new brand for Platform.sh) rallied around an ambitious 30‑day deadline, executed a seamless migration in the middle of summer holidays, and built a partnership that continues to drive innovation today.

1. The tipping point: outages after the Magento 2 upgrade

Isabelle Sarrazin, CEO at Easypara, opened the conversation by recalling the “trigger event” in late 2022:

• Frequent downtime after the Magento 2 launch was hurting revenue and brand trust.
• Root causes ranged from technical complexity to missing incident‑response procedures.
• A decisive change was non‑negotiable.

“We had significant periods of unavailability. That accelerated our search for a partner who could guarantee stability and performance.” — Isabelle Sarrazin

2. Choosing the right allies

Easypara began scouting for solutions in early 2023. Two key factors shaped their choice:

1. An existing Upsun ↔ Dn’D alliance
   Dn’D was already an Upsun Solution Partner, bringing deep Magento expertise.
2. A unified, three‑party model
   Upsun would manage and secure the infrastructure, Dn’D would own application delivery, and Easypara’s team would focus on business growth.

“We don’t do ping‑pong tickets. All three teams stay in sync, almost in real‑time.” — Antoine Kociuba, Tech expert, Dn’D

3. The 30‑day challenge - during summer vacations

With incidents mounting, Easypara set an aggressive goal: go live on Upsun in 30 days (June → July 2023). The constraints:

• High traffic & large catalog – a multi‑million‑row database, thousands of product images and invoices, numerous scheduled jobs.
• Summer staffing – only one lead developer from Easypara could be dedicated full‑time.
• Learning curve – Easypara’s engineers were discovering Upsun’s console, Fastly CDN, and Blackfire profiling for the first time.
• Yet the teams delivered on time.

5. Results so far

Although precise numbers will be shared in a forthcoming case study, the webinar speakers highlighted:

• Dramatic reduction in unplanned downtime
• Improved page‑load times under peak traffic
• Operational peace of mind for the Easypara IT staff, who can now focus on features instead of firefighting
   

6. Beyond the migration: a TV campaign & continuous innovation

The partnership did not stop after cut‑over. In autumn 2023, Easypara launched a national TV marketing campaign that triggered fresh traffic bursts. Upsun and Dn’D tuned the architecture in advance, proving that the collaboration model scales with the brand’s ambitions.

“The same tri‑party approach carried us through the TV push. It shows this isn’t a one‑off project; it’s an ongoing relationship.” — Ludiwine Fouquer, Upsun

7. What’s next?

• Enhanced observability – deeper use of Blackfire and Upsun Metrics.
• Feature teams on Upsun – Easypara plans to adopt preview environments for every new initiative.
• Continued joint webinars – Expect follow‑ups focused on performance benchmarking and campaign readiness.
