I am very keen to test the exiciting new Frozen Throne version. Thanks for the efford to all you developers have put their time into this. Much appreciated.

I have now downloaded the new version and been through the file list. I have also looked through the installation guide. I am however still unsure about the consequence of just copying all the new downloaded files to my server, because I think that any customisation that I have made over a period of time will disapear completely.
Just a simple example: There is a new user.ini file included in the new version. Copying this to my existing installation will make all my usual admins disapear.
Yes - I know i can make a copy of the old installation and copy/paste part of the old user.ini to make up for this, but isn't there an easyer way?
Looking at the date of some of the files in my download, it would also appear that a large proportion of the files have not been updated, since the show dates going back to 2004. I take it that these files do not need to be replaced?
I have looked around checking for a list of files that would be essential for the new update. This would enable me to limit the number of files I would be replacing. Is this a worth while option?
Hoping for a bit of assistance with this.
