I'm in the process of migrating a large, complex site to Craft.
I've reached the stage where I like to install Craft in parallel to my existing CMS with the intention of allowing users to help me check the content is migrated correctly.
It's also with a view to keep parts of the existing site in the current CMS and migrate them later.
Do you have advice on how to best do this? How would I redirect requests for different parts of the site to the correct CMS?
