We have experience owning and managing large-scale, high-complexity enterprise migration projects across a range of industries and platform environments.
Our dedicated enterprise SEO migrations team will work with you to determine exactly what performance needs to be retained across your entire digital estate and partner with you as your SEO stakeholder throughout every phase of the project. POLARIS are experts in:
/ Benchmarking performance at scale, covering thousands of URLs, multiple site sections, and revenue-critical landing pages, to establish precisely what must be protected before any change is made
/ Working with your internal marketing, development, and IT teams to build a migration strategy and site architecture that reflects both your business goals and your SEO requirements
/ Evaluating and mapping content at scale, ensuring high-value pages, product catalogues, resource libraries and cornerstone content are migrated without loss of search equity
/ Technically managing the complex challenges that enterprise migrations introduce, from legacy redirect chains and parameter handling to faceted navigation, JavaScript rendering and enterprise CMS constraints
POLARIS delivered a comprehensive, multi-faceted SEO migration for T-systems' enterprise consulting arm, Detecon, safeguarding existing search performance and domain authority. The successful project resulted in a 133% increase in daily site visits post-migration.
Detecon Enterprise Website Migration
A proven process designed to manage complexity at scale, protect performance across large digital estates, and give senior stakeholders complete confidence throughout an enterprise site launch. Our migration service is carried out using a 5-stage framework that has been refined through hands-on experience with large-scale, multi-stakeholder migration projects.
1. Performance Analysis
We benchmark your existing visibility, traffic and key landing pages at scale, across all site sections, subdirectories and business units, so we know exactly what must be safeguarded, and at what level of priority, during your enterprise migration.
2. Content Migration
We map and validate every important page, journey and content asset across your digital estate to ensure the new site retains the full SEO strength of the current one, including enterprise-level taxonomy structures, product catalogues and resource libraries.
3. User Tracking & Search Engine Compliance
We set up and verify tracking, analytics and search engine profiles across your enterprise environment so your data stays accurate throughout the transition and search engines fully understand the structure of your new site from the moment it launches.
4. Technical Analysis & Changeover
We assess the technical health of your new enterprise build, covering crawl budget management, JavaScript rendering, faceted navigation, redirect architecture and CMS constraints to deliver a clean, disruption-free changeover with every URL correctly mapped and preserved at scale.
5. Post-Launch Monitoring & Reporting
We manually check redirects, user journeys and search visibility across your entire digital estate after launch, providing structured performance reporting to internal stakeholders and resolving any issues before they compound into sustained ranking or revenue loss.

POLARIS accelerated the re-development of Milton Park’s new website as they were undertaking a slight re-brand on their current site. As identified by our SEO Agency team, the website had multiple technical and content issues which held back their organic visibility due to an inherited website with fundamental legacy issues.
Internal development teams are equipped to build and deploy large-scale websites, but they are not responsible for (and rarely resourced to manage) the SEO implications of an enterprise migration. At enterprise scale, the consequences of unmanaged SEO risk are proportionally greater: thousands of URLs, multiple business units, significant organic revenue streams and complex stakeholder environments all amplify what can go wrong. A specialist SEO migration agency provides the independent oversight, technical expertise and cross-functional stakeholder management that an internal team cannot objectively provide for itself, ensuring that performance is protected rather than recovered after the fact.
Enterprise migrations are among the longest and most complex digital projects an organisation can undertake. Timelines vary significantly depending on the size of the digital estate, the number of stakeholders involved, the platform being migrated to or from, and the volume of content requiring audit and mapping. Our 5-stage framework is structured to integrate with your internal project governance and we will provide a detailed project plan with clearly defined milestones at the outset. Enterprise migrations are rarely measured in weeks; a realistic, well-managed timeline is one that does not compress critical SEO stages under the pressure of a fixed launch date.
Enterprise CMS platforms such as Sitecore, Adobe Experience Manager, Salesforce Commerce Cloud or SAP Commerce have built-in migration tooling and URL management features, but these are not a substitute for active SEO migration management. Platform tooling can move content and map URLs within a defined ruleset, but it cannot audit your existing SEO performance, identify at-risk pages, validate the quality of redirect implementation, or manage the post-launch monitoring required to catch and resolve issues before they impact rankings. Tooling executes; strategy protects.
Stakeholder governance is one of the defining challenges of an enterprise migration and one of the areas where SEO performance is most frequently put at risk. In large organisations, decisions that affect search performance, site architecture, URL structure, content prioritisation, launch timing, are often made by teams who are not aware of the SEO consequences. As your dedicated migration partner, we establish a clear SEO governance framework at the outset of the project, defining decision-making authority, escalation paths and review checkpoints that ensure SEO has a seat at the table throughout. We communicate in the language of your internal teams so that performance risk is understood and managed at every level of the organisation.
Site consolidation migrations are among the highest-risk projects in enterprise SEO. Each domain or subdomain being consolidated has its own authority, ranking history, backlink profile and indexed content, all of which must be carefully mapped, redirected and preserved in the destination site. Consolidations also frequently involve competing stakeholder interests, where different business units may have different priorities for which content and which market positions are retained. We treat each source domain as its own migration workstream within the broader project, with individual performance benchmarks and redirect strategies, ensuring that no business unit's organic performance is sacrificed in the process of consolidation.
By establishing detailed performance benchmarks across every section, subdirectory and business unit of your digital estate, we identify the structural and content elements that are most critical to your organic performance and revenue. This ensures that high-value assets are prioritised, protected and optimised throughout the transition to safeguard your site's authority, commercial viability and search prominence at every level of the organisation.
By scrutinising the proposed architecture of your new enterprise site against this inventory and benchmarking against competitor performance across your key market segments, we ensure the migration preserves your existing strengths whilst identifying the structural and content opportunities that the new build should capitalise on from day one.
For large organisations, data continuity during a migration is not simply an analytics concern but a business intelligence requirement. Gaps or inaccuracies in post-launch data can misrepresent performance, delay issue identification and undermine the internal reporting that drives decision-making.
Additionally, we ensure full compliance with search engine guidelines across your entire estate, covering XML sitemap structure, robots.txt configuration, canonical implementation and Search Console setup, safeguarding your long-term organic visibility from the point of launch onwards.
This covers crawl budget management, JavaScript rendering, faceted navigation, pagination handling, redirect architecture, legacy parameter management and enterprise CMS constraints.
We produce a comprehensive redirect strategy that maps every URL in your existing estate to its correct destination on the new site, validated and tested at scale to ensure the integrity of your search equity through the transition. This proactive, exhaustive approach is what separates a well-managed enterprise migration from one that requires costly recovery work in the months that follow.
We provide formal performance reporting to your internal stakeholders across the four weeks post-launch, delivering the data, insight and narrative that senior teams need to understand the performance trajectory of the new site. Where issues are identified, we triage and resolve them in priority order, ensuring that any post-launch disruption is addressed before it compounds into sustained ranking or revenue loss.
