Upgrading SpamAssassin (and Perl Modules)

[Nathan Johanson]

This may be a little OT, but you guys are so helpful...

An easy question. If I have already installed the SpamAssasin 2.31 via tar ball. And I want to upgrade to version 2.43, is it a simple matter of downloading the tar ball, running make, make test, make install, and installing over the top of older version? The same goes for updating perl modules (it appears to just install over the top, but I'm curious what's going on behind the scenes).

During make install of a new version, does it remove the old files first before writing the new ones? Or does it simply overwrite them? And if so, is there any danger of leaving older, defunct files behind that could bite me in the ass down the road? Should I try to clean out the old version first? 

Thanks in advance!

Sincerely,

Nathan Johanson
