Yes. And 6 years (2006 the migration started) is far from "nearly a decade" if I can trust my math. The Munich migration has been attacked, downplayed, doomed for as long as it is running. The article here gives some hard data based on a reply to a request from the opposing political party in Munich that hoped to get some ammo to attack the migration. Instead they got well researched data that shows the opposite - so far they are absolutely in budget, saved 30-60% of costs (as planned), reduced support costs (as hoped) and created a side project called WollMux that tremendously helps in migrating the VB cruft and macro ridden templates that accumulated over the past 10-15 years into a reusable library of centralized functions.
They "deduplicated" a lot of redundant forms (one little example: The act of asking for PTO was implemented in 45(!) different forms depending where you work in Munich - now it is one single unified service for all) and by centralising stuff they can now do useful statistics that simply didn't exist before.
The focus on Open Standards starts saving a lot of time and money in the archives already.
