Case study · Technical takeover and support

Taking over a consultancy website and keeping it running.

We restored Oppenheimer Conseil’s existing website, took over hosting and connected its contact form. Subsequent support covered website addresses and a sitemap including French and English news added through the administration.

The starting point

The project context.

Oppenheimer Conseil supports executives, businesses and organisations facing complex administrative, institutional or strategic situations. Its website presents the firm, expertise, intervention scenarios and news in French and English. Our work covered taking over this existing application and keeping it operating over time.

Client website

Expertise, situations and a way to explain your needs.

The public website presents the firm’s areas of work and provides a route to submitting an enquiry. The screenshot shows the homepage online on 21 September 2026.

The challenges

What needed to be addressed.

  1. 01

    Bringing the existing website back online

    Start from available source files and preserve stored content, then verify public pages and assets on the hosting taken over.

  2. 02

    Connecting enquiries to the firm

    A contact button is not enough: the form needs to send messages to the right address. Its connection needed to be checked through to receipt.

  3. 03

    Tracking genuinely published content

    The sitemap used an initial article list and omitted items added through the administration. It needed to match the News sections in both languages.

What we did

The work, step by step.

  • Backed up content and took over the website from existing sources, preparing a standalone Next.js version for hosting.

  • Restored service on the client’s server, configured the web server and HTTPS, then checked public pages, news and the English version.

  • Connected the form to the firm’s email, updated public .fr addresses and verified a submission through to receipt.

  • Checked redirects from old .com addresses to their .fr equivalents and canonical address consistency.

  • Fixed the sitemap to use published articles in each language, applying the same selection rules as the News sections.

  • Removed artificial modification dates from the sitemap, checked referenced pages and submitted the corrected file to Google Search Console.

This project covers takeover, restoration and technical support for the existing website. The original creation of its visual identity and content is outside the scope presented here.

Taking over an existing application

Hosting, contact and page crawling.

The project brings together specific improvements to website operation, with checks after each release.

  • Next.js application

    The standalone version runs the application on the client’s server behind a web server handling public HTTPS access.

  • Content preserved

    PostgreSQL database content was backed up before restoration. News continues to be managed by the existing application.

  • Bilingual sitemap

    Each language uses its own article addresses. The list refreshes to include publications added after the website build.

For visitors

What you find when you arrive.

  1. 01

    A clear activity from the homepage

    The opening screen announces advice and support for complex administrative, institutional and strategic situations.

  2. 02

    Several ways to understand the offering

    Navigation provides access to expertise, situations, FAQ, case examples and firm news.

  3. 03

    An enquiry accessible from navigation

    The “Tell us about your situation” link leads to the submission journey. The telephone and French and English versions remain visible at the top of the page.

Who visits, and why

  • Executives and businesses

    Understand the matters handled by the firm, read the situations presented and access the form to explain their needs.

  • News readers

    Read publications in their language and find other firm content through navigation.

  • Visitors using old addresses

    Reach the corresponding .fr pages through redirects retained from the .com domain.

Verified results

Documented operation, from the public website to the sitemap.

These results describe the work and checks completed. They are not measurements of traffic growth, Google ranking improvements or revenue.

  1. 01

    A public website restored

    The application and its content were redeployed on the hosting taken over. The homepage was accessible over HTTPS on the .fr domain during checks on 21 September 2026.

  2. 02

    A connected and tested contact form

    Form delivery to the recipient’s mailbox was verified on 3 September 2026. This check concerns sending functionality and does not claim to measure business enquiries received.

  3. 03

    News included in the sitemap

    The 19 September fix includes publications from the administration in French and English. Google reread the corrected sitemap without errors; page indexing is monitored separately.
