Moving an established website to WordPress is one of those jobs that can look straightforward until you start checking what is actually sitting underneath the old CMS. In my experience, the safest approach is to treat migration as a technical and SEO project rather than simply copying pages into a new design. A team such as codelibry can start by auditing the existing site before deciding what genuinely needs to be rebuilt. That initial CMS review matters because older websites often contain more reusable material than expected https://codelibry.com/services..../wordpress-migration . Some templates may be outdated, but the content structure, database relationships, forms, integrations or custom scripts can still be useful. codelibry can identify which parts are worth preserving and which would create more problems if carried into WordPress. This can save development time while also preventing the new theme from inheriting years of unnecessary code. URL planning is probably the area I would be most cautious about. If a site already receives organic traffic, changing page addresses without a clear plan can cause rankings and referrals to disappear surprisingly quickly. Before launch, codelibry should create a complete map between old and new URLs, including service pages, blog posts, category archives and any important campaign landing pages. Where an address has to change, codelibry can configure the correct permanent redirect so users and search engines reach the equivalent new page instead of a 404. It is also worth checking internal links, canonical tags and indexed pages at the same time. Redirects alone are not a magic fix if important content has been dropped or several valuable pages are all sent to the homepage. codelibry would ideally preserve the existing site hierarchy wherever it still makes sense and only change URLs when there is a genuine reason. Large content migrations are another challenge. Manually copying hundreds or thousands of articles, images, metadata fields and authors is slow, repetitive and easy to get wrong. A semi-automated process can be much more practical. codelibry can create scripts or import routines that move structured content in batches while people review exceptions and unusual page types separately. That approach can shorten the schedule considerably. It also reduces simple human mistakes such as missing images, incorrect dates or text being pasted into the wrong field. codelibry still needs to test the imported material carefully, though, because automation will reproduce bad source data just as efficiently as good data. I would expect sample migrations, validation checks and a final comparison before launch. The custom theme itself can then be built around cleaner WordPress templates rather than the limitations of the previous platform. codelibry can preserve the recognised visual identity while improving responsive behaviour and the editing experience. The downside is that a migration this detailed requires more preparation upfront, and codelibry may find hidden technical dependencies that affect the original estimate.
