upgrade elxis

[openita]

I would like to ask for a little information.
Should I upgrade from Elxis: Elxis CMS v4.1 Poseidon for Elxis 4.2 Icarus, but I would like to know if doing the update I would lose all the graphical changes I've made in the CSS for Elxis CMS v4.1.
Thanks!

Updates NEVER alter your site's data or style. It is always safe to update.

There is only 1 thing to keep in mind regarding v4.2: It has a brand new default template named Flex and some changes in modules/plugins html and css. Your 4.0/4.1 template will be fine in 4.2 but you might have to perform small css improvements for some core modules/plugins if you want everything to be 100000% perfect.
