downgrading

[Ronan <r....@qub.ac.uk>]

Is there an easy way to downgrade spamassassin?
we currently run 2.6 on our mailhubs and i want to upgrade to 3.0.
mailhubs are solaris 8 sparc sunblade 100s. (3)
We use sophie and the daemonised version of spamassassin with SAV.
I want the option of downgrading back to 'working' version should 
anything go wrong....

thanks

Strange question, but are your drives mirrored?  There's an easy way to
downgrade software if you have mirrored drives  ;+).

Make a backup copy of the Bayes database files before the upgrade.  The
database will upgrade to 3.0, but it is then NOT backward compatable.  So
save the old version to reload, or you will have to start from scratch.

Wouldn't hurt to save your local config files if any, since you will have to
change a half dozen lines for 3.0.  Or you could back out the changes
manually, since they are minor.

Other than that, some of the startup options changed, mostly on spamd.

Of course, save your 2.63 codebase also, since it is probably easiest to
nuke it and start with a clean install.
