Moving from 4.0.11-gamma to 4.0.18

[Chris Fossenier]

I am planning a server upgrade and would like to update MySQL in the
process. The preferred plan is to:
 
1. Upgrade the server Operating System.
2. Copy the MySQL files to the new storage system.
3. Install MySQL 4.0.18 and point it to the old MySQL directory
4. Start 4.0.18 and have no problems.
 
I'm guessing it's probably not that simple. Any insight into this from
someone with experience would be appreciated.
 
Thanks.
