I totally agree, it is not advisable to shut down operation while
maintenance is being done, as I understand in manufacture faiover
infrusttructures allow maintenance to be done on the run
However, two entities with the same name could cause enourmous
disruption to processes somehwer along the line, especially when
databases get merged (argh) (02)
As 'system analysts' we would weigh the loss caused by the disruption
of two hours shutdown in comparison to
incalculable disruption if two processes cross wires, or even small,
constant losses caused by ongoing inefficiencies in deadling with the
duplication and redundancy
Would mend on the run not be possible, we would advise to chose the lesser evil (03)
