I've been experimenting with a WP installation and have been populating the database using an unused domain extension as part of my hosting package, but I now want to install what I've created with the domain extension (in my case, I'm moving it from a .biz domain to the primary .co.uk domain). I am about to place the WP files and folders into the root of my webspace, where an existing html website is so be replaced by the WP based site.
My question, therefore, relates to .htaccess files. I already have an htaccess file with lots of stuff in it and which I don't want to lose. In moving the WP files into the root space, will it be OK for me to simply combine the contents of the two htaccess files and leave it where it is? WP won't periodically over-write the data or anything, will it?
I will, of course, experiment after backing up everything I have just in case, but second-opinion input would be appreciated!
