I had MySql 4.0.9 installed on a linux machine but i messed up the server while upgrading a new kernel. Fortunately, I had a backup of the entire mysql installation directory. So I copied it over to a different machine and this machine has MySql 4.1.0 installed. I assume that since I have the "data" directory, all the database I have been using can be recovered. The problem is I cant seem to find any information about how to go about this. I would really appreciate if any1 can tell me where i can look for how to do this. Many thanks to you all!
