I'm pretty new to WordPress and are still in the experimental phase of playing with themes, selecting and configuring plugins. I now have an idea of what my site should look like and what configuration to use. Next step is to come up with a process and structure how to manage my site configuration and what else needs to be done to keep my site working and resilient to problems. Unfortunately, Google hasn't come up with many answers to my questions:
How do I best separate design, test and life sites? I want to have at least two: design/test and life. How do I transfer configuration changes from one site to the other. How can I generate test content, can I copy life content to the test site. How will it work if I split design and test as well?
How well are configuration and content separated? Is it possible to just copy the wordpress directory, change the database name and have a working second site?
How to manage site backups seems to be covered in the documentation?
What other pitfalls are out there from a purely operational point of view, user and content management being a whole different animal?
Do I have to think about site growth and performance already or can I ignore this until I get X number of hits, Y number of users. How big are X and Y?
Is there any information out there for this kind of questions? Websistes? Literature?
Thanks for your help.
