my first install of ruby was on tiger mac os x 10.4  
i just finished on 10.5

migration files are showing up as  
20080611121124  
instead of 1, 2, 3, 4

can i change this.  
i have to move an app and database to the new server i am worried that  
there will be problems with rake if i don’t find a way to correct this.

This is normal. Rails 2.1 has a different migration naming scheme. as  
long as the host you move to has rails 2.1 (or you freeze rails into  
the app) you’ll be fine.
