[FX.php List] [Off-ish] Advice on FMS8A -> FMS9A migration strategy

[Bob Patin]

Troy,

I'd go ahead and set up the same site on the other machines; here's  
how I might do it:

Duplicate the site and the database, and install it all on the new  
machines.

Run the site on the new machines before switching any DNS, to make  
sure it's working properly.

Once you're sure it's working right, then you could do this: on the  
OLD web server, put a redirect page to direct traffic to the new web  
server.

Then, once that's all set up and you know it's working, you could  
switch the DNS to point to the new web server, and move over your  
actual production database.

Hope that helps take care,

Bob Patin
