Changing theme and working around caching systems.

Currently I have a wordpress installation on a third party theme that I want to transfer over to the default Twenty Eleven theme.

I’m on cent os 64-bit running php 5.3.6 with xcache 1.3.2 and w3 total cache for my WP installation using xcache.

I tried simply changing the theme in the dashboard and it broke a lot of things. I ended up reloading everything back to what it was.

I have 8 javascript files listed for the current theme inside of W3 Total Cache minify settings. I’ll have to remove those of course.

What should be my next steps? Disable W3 Total Cache? Or keep it enabled?

Any tips/advice?
