In a properly managed production environment software upgrades of any
size should not be an ordeal in the least. One can run their own
package repositories for distro of choice, and segregate testing from
production for the various components being run. Of course one's own
tagged software can be packaged and distributed as well. Anything that
doesn't work on the testing environment shouldn't be pushed onto a
production system. Make it simple to switch a "production pointer" from
one system (or cluster or network) to another, and back, and even
unexpected incompatibilities can be quickly reversed. Testing becomes
production, and the old production system(s) become the new testing
Then again, I suppose we're talking about improperly administered
environments almost by definition in this thread, so, um, carry on.
