Working notes
What needs an inventory before a website migration?
The page count does not tell you whether the move is complete. A migration needs to account for the relationships and services around the content too.
The short answer
Inventory more than pages. A migration can depend on images, downloads, products, redirects, forms, email and other services around the site.
Why it matters
It is easy to recognise a missing page. Missing image relationships, forgotten downloads and a changed URL are less obvious until somebody needs them. Before moving a site, I'd establish what exists and what has to keep working.
Content and relationships
List the page types, products, variations, categories and any custom fields that matter. Record how they relate to each other. A body of text without its parent product or featured image may not be a useful migration.
The image-recovery work is a good example of why copying media files and restoring their relationships are separate tasks.
URLs and assets
Keep an inventory of existing routes, images, attachments and downloads. Decide what is staying, what is moving and what is genuinely being retired.
Where a route changes, agree the appropriate destination rather than sending every old page to the homepage. Where content is missing, check what remains before deciding it must be recreated.
The services around the site
A domain change may affect more than the web pages. Email, forms, integrations and other services need named responsibility and suitable tests.
A domain move with email continuity is a different scope from simply uploading a replacement website. I'd make those dependencies visible before the switch.
Tell me what you need to sort out
If you need this checked or fixed on a real site, send me the URL, a safe example and what you are trying to achieve.
Write the acceptance checks before moving
Pick representative journeys and records. Decide what counts as a successful transfer, who signs it off and how the old and new versions will be compared. Keep the recovery route available until the agreed checks pass.
A clear brief helps establish those boundaries. Where the export is incomplete, recovery work may need its own investigation.
HAVE SOMETHING AWKWARD?
Tell me what you need to sort out
Send me the URL, what is happening, what you have already tried and what a useful result would look like. A small anonymised sample is enough to start - do not send passwords, credentials or sensitive customer data.
