Very contingent on the type of site, Daniel.
I am currently working at one that has the dubious "advantage"
of being on DMT + RBO with 9ir2!!!!
The previous dba - for whatever reasons that don't matter here -
decided
to leave the schema and the data at V7 while upgrading the db
software to 9ir2. WTF for begs explaining, but let's ignore it...
With the result that I now have a headache of dinossauric proportions! And an app that "only works with RBO", or so the development manager has been led to believe.
So, my mission (should I accept it) is to:
1) convince the DM that contrary to what the previous dba told him,
CBO in 9ir2 is darn good.
2) convince the DM to do testing of the app with 9ir2 + LMT + CBO.
3) convince the CTO that all this is worth doing when all
he hears is that "MySql is free therefore must be good".
4) find a slot somewhere in a 24X7X365 system to do the necessary
manipulations to get rid of the old stuff and put in the new
with minimal disruption.
5) write a plan to implement 4) above in such a way that if ANYTHING
goes wrong, even the proverbial pointy-hair damager can set
things back the way they were.
Meanwhile, the backups are churning along with good old crontab/cpio. Do you think for a second I'm going to touch them AT ALL before I fix all the other crap?
NBW!!! (No-Bloody-Way!!!)
