1. Can I create a copy of my XF install onto a sub-domain (passwd protected to adhere to XF rules), for testing purposes, using the same database? I will use this for testing add-on compatibility and styles
2. Assume the answer to above is Yes, then could I also upgrade the test site to 1.2beta (which I assume make DB changes) without affecting the operation of the production site? Thusly, is a XF 1.2 database compatible backwards compatible when using XF 1.1 ?
