A little Scenario for you - A mail server running on linux(debian i believe). The mail server is running qmail and obviously some pop/imap software which i'm not familar with. The mail server is currently located on the premises, which isn't a good thing. For reason of security and redundancy this server needs to be moved into a Co-location. The current server is essentially a Home build "Server" in a Full tower case. However we want to use a spare rack mounted machine we having lying around.
Now to the actualy question
What are the implications of taking out the HDD's in the current mail server and putting them in the new Rack mount server?? I'm guessing that linux isn't going to like that much?
One of the theories a collegue came up with was just try and if it doesn't work just put them back. However i find this a little dangerous as this is a production mail server. I'm rather new to linux but i know that windows 2000 tries to change when you put it in a new system. If the same occures in linux unsucessfully on the rackmount server i would assume it would leave the system in a unusable state - not working in the new systems but also not in the old system.
Any suggestion or advise would be appreciated
