Can I change index.php to a different name?

I've decided that I like Dolphin so much on my one domain, that I want to get a second license.

However, I am currently running wordpress on that domain and it uses index.php.

Can I temporarily change dolphin's index.php to something else like home.php or dolphin.php while I work on customizing it in the background? I don't want anyone to see it until it's ready and all my data/pages are converted over to Dolphin.

Created a subdomain or install dolphin in a different directory outside of root

I'd like it keep it in root as I will be deleting wordpress when I am done customizing Dolphin. Dolphin will run my entire domain.

No you can't. Not without a lot of changes throughout the script that go back to index.php. Not to mention there may be other files other than index.php that may already exist like .htaccess which dolphin will not function properly without it.

Putting it in a sub folder is the best way. It can be moved after.

A little information on your hosting set up would help but as stated, it is easy and simple to move the Dolphin later from the subdirectory.  You simply need to make a few edits in the header.inc.php file.  So go ahead and install Dolphin in a subdirectory, build your site and when you are ready to move it you can come back here if you have problems.  By the way, there are posts in the forum about moving Dolphin if you want to get some assurance first that it is easy.

To be perfectly honest, having dolphin even in a sub folder off a WordPress site may prove to be problematic. There have been posts here in the past about WordPress rewrites interfering with dolphin. So you may find it has to be done in it's own folder out of the WordPress root.

Thanks!

Thought I'd ask, just in case there was a way to do it.

I'll install in a sub-directory, customize the design, convert my current data & pages to dolphin and then move it all to the main directory when ready. I'll check the forums for info on edits to header.inc.php when it's time.

I'm on a Rackspace cloud server with root access and everything.

I almost forgot about WP rewrites.

I'll just create a subdomain, and then when ready I will move it all to the main domain. That will prevent interference with WP. Mysql database will remain the same on localhost, but all files will be moved.

Running Apache or a different webserver?  Oh, are you running under a cPanel setup?  There are ways to get out from under cPanel setting the domain to the root of the web space.

Anyway, in this case you don't need to install it to a subdirectory under anything.  You create a new directory for your Dolphin and setup a subdomain to point to it.  You can do all your work under that subdomain and later move it to the main domain.

You posted the same while I was composing my response :-)

Yep.

Apache. No cpanel. Webmin.
