This makes more sense. But even then they would surely transfer data from the old system over.
All you gotta do is snap your fingers!
Moving data from system to system is a massive undertaking. It probably needs to be restructured, and decisions made during the process will be found to be imperfect and adjustments will need to be made along the way.
Then you have to change all the connections to other systems and recreate the existing reports and by the way the changed structure impacts all of that and you need to revisit why you have all this stuff snd why don’t we just leave it alone after all.
There is a reason that legacy systems stick around. I’m sure they have legacy mainframes with financial data. At my state office we have a financial mainframe we have been wanting to get rid of for over a decade and while we have peeled off what processes we can there is still a ton left to do. Nothing about it is easy compared to creating something new from scratch, in fact transitioning to a new system to replace an old system is probably ten times as much work. Not to mention you still have to use and maintain the old system the entire time!
I have more space to hang and it is easier to get to the one I want than if they were stacked in a drawer. This includes tshirts, which make up most of my hanging shirts.
Plus my lack of folding skills means a drawer full of shirts would be a lumpy mess in short order.
