Hi
I have just purchased the paid version of Oxygen template. My site had been set up over the last couple of months using the free version (version 2.0 on a Joomla 3.2 site).

If I install my downloaded paid version will it overwiite the existing template and keep all my CSS tweaks, configuration settings etc ? Or will it install as a separate template meaning I will have to do all my tweaks again?

If it installs as a separate template, is there anything included in the paid version that isn't in the fee version?
If not, can I just then remove the "Joomla Templates by Joomla51.com" text by editing a certain file?

Thanks
