When migrating WordPress sites, eg from Staging to Prod, I might want to use an extension like All-in-One or UpdraftPlus.
Not sure, but my guess is that those migrate everything … which is good for initial deployment, but not great for ongoing updates.
What I’ll want for ongoing updates is to be able to copy across whatever’s changing (eg themes, menus, etc) from Staging to Prod, but keep the production data (posts etc) intact. Not sure how to do that, just yet.
