I started thinking about how many personal computers I have owned in that time and it has to be close to 20, covering the following operating systems:
Windows For Workgroups 3.11
I have used this same Notes database, with few changes on each of these systems. Oh, and there was no data conversion or migration. (Unless you call replicating a Notes database to a new machine a migration.) For people in the yellow bubble this is nothing new. For people working with other products and platforms this may be a novel concept.
What brought all of this up is the fact that I'm writing a paper on enterprise content management and I have been reading about the nightmares of managing and migrating content. For the most part, this has simply not been an issue. That's productive!
