Hi:
I am going to use 5 new domain names. Each one will have a different domain name and all of them in the same hosting.

So, if i understand correctly:

1) make a backup of my database

2) just copy all of the files of my original store but changing the two configure.php

3) If I create new databases, how do I use my saved database backup of my original website?

4) How do I use fix_cache_key.php?

Thanks to all of you!!
