How to Downgrade from Wheezy to Squeeze

["Garry" <garry@gdconn.com>]

Is it possible to downgrade from Wheezy to Squeeze?

The reason I want to downgrade is because I am trying to install Openfire and unfortunately:

openfire pre-depends on sun-java5-jre | sun-java6-jre | default-jre-headless | openjdk-6-jre

- - I would prefer downgrading if it’s possible. 
- - I wouldn’t mind keeping Wheezy if I could get the pre-depends installed. 
— - If downgrading isn’t an option; can someone help me with remote installation (server is located in the attic; I’d prefer not climbing up there to retrieve it.)

Thanks in advanced to anyone and everyone willing to help!
