Xsitepro to Wordpress how do I do it?

There's a few aspects to this:

1) If you install WP to the webroot of wherever your site is, probably nothing will happen...your existing site's index.html will override WP's index.php so your old site will display.

2) Your problems will come when you try to make the WP's URLs the same (.html) as your old pages. 2 identically-URL'd pages are going to throw up problems. Also, while your old site is holding pole position, your wordpress 'home' button will take you to http://yoursite.com/ ...and this will of course take you to the homepage of your old site.

3) Building it in place can be done, but there are problems. Some potential ways of approaching it are:

i) Build it in place, but use a different permalink structure while building. Then when you've done it all, rename your old site's index.html to old_index.html and *then* change the permalink ending to match up with your old site. You will also have to add the homepage in at the last minute as you won't have seen Wordpress's one up until then.

ii) Build it somewhere else in another directory, then when you've finished wildcard server redirect from
http://yoursite.com/*
to
http://yoursite.com/wp-directory/*

iii) Build it in another directory. Back up the files. Back up the database. Do a search-and-replace on the database backup: Replace:
http://yoursite.com/wp-directory/
with
http://yoursite.com/
...then rename your old site's index.html to old_index.html; install wordpress; upload the files (you shouldn't have too much in the way of conflicts, but if you do, rename the old version of the file to old_*.*); restore your modified database and you should be good to go.

UPSIDES AND DOWNSIDES:
Method i) can be complicated.
Method ii) is simplest, but can go wrong and is a little untidy
I like method iii) myself, but that requires enough confidence to mess around with database backups.

Whatever method you use, it's always a good idea to leave your existing site in place and to 'turn it off' by renaming the index file. That way if things go titsup, you can always rename the index file back again and get your old site back.

The most important thing to pay attention to is the fact that your WordPress permalinks will be different from your existing site's page URLs and, therefore, you need to make sure that all of the pages on your XSP site are re-directed to each equivalent page on your new (WordPress) site.

I just realized that I have reseller account, duh.

Can't I just make a new account in my WHM. and just have it as the 123.344.55 number url thing.

Then build up WP on there, workout all the links etc then when done, point domain at this new server location etc?

I think that sounds like it would work???
