We have a collection of sites with similar purpose, and the content from one (site A) has been partially copied across to another (site B ) which has led to a request to decommission site A.
The site editors have communicated that they don't believe they reused any images / files from site A on site B - but I'm wondering if there is a way to check that? These are files which are under __data etc so I can't just grep the access log for requests for /siteA/
Also wondering what other tips people might like to share on decommissioning Matrix sites?
