Hi every one,
Reading all ideas about solving issues with upgrading systems from working systems are more or less ideas of ad choc solving some issues or even more or less reinventing the wheel. IMO all those ideas will not solve anything and will only increase total level of entropy. After this will be necessary sooner or later add even more ad choc workarounds and so on ..
I've mention already that some solutions are close to reinventing the wheel.
Why? Because they've been solved long time ago. To be more precise more than decade ago.
