My team and I are working with a client who has an existing WordPress site with a fair bit of content and a custom theme they built. It is a group blog, meaning it has several bloggers all around the world who are adding & editing content all the time.
Our job is to create an entirely new theme, with quite a few new features. Some of these features will require new custom widgets, plugins, and database fields.
We're currently working off our own development machines and integrating them into a single development server. All code is versioned in SVN. Our appointed DBA is manually merging any database changes into the dev DB right now, though hopefully he'll be able to automate that soon.
We just started talking about our production release process. Meaning: once we're done, how are we going to get all of our custom code onto the production (the live) server smoothly and with as little disruption as possible?
We have a few plans in mind, but I would love to hear how others have tackled this issue too. Are there any best practices to follow or known pitfalls to avoid?
Thanks in advance!
