Recommended method for updating a live site with new content/assets/regions
If I have a site that's already live and has edits, but I've created new pages with new regions and assets on a dev site. I'm wondering what the recommended way to migrate this to the live site is.
The only way I can figure out is to upload the new PHP/template files and then recreate all the content and upload the assets...but this seems very repetitive and leaves the website in an awkward state while this is happening – not the best to a busy site.
I've found the page about making a site live (https://solutions.grabaperch.com/development/how-do-i-move-a-perch-site), but I'm not seeing anything about later on.
What are you doing? Any recommendations/processes?
