I've been running a blog via WP 2.6.1 in a sub-folder on one of my domains i.e. mydomain1.com/blog, which I plan to move to mydomain1.com
I'm also ready to update from WP 2.6.1 to WP 3.3.1 and I'd ultimately like to add WP and/or BuddyPress to multiple domains (all separate entities & topics) i.e. mydomain1.com, mydomain2.com, mydomain3.com.
My web host says they can "upgrade my account" to the required versions of PHP & MySQL; so I've backed up my current blog's Database & Files and disabled my plugins but have a few questions:
1) Which do I do first; upgrade my hosting account to the required versions of PHP and MySQL or update from WP 2.6.1 to WP 3.3.1?? Or does it even matter?
2) Currently, I go to mydomain1.com/blog/wp-login.php to administer my one blog. Where will I go to administer WP and/or BP on multiple domains after adding them?
3) My current theme doesn't appear to be available in the WP Theme Directory, how will updating to WP 3.3.1 affect my current them?
4) What else should I be concerned about before moving forward?
