OOCL and JP Morgan are still using Envy (although I've heard that JPM has
purchased a license from IBM and maintains an in-house fork with the latest
version of VW). I believe UBS has migrated to Store, but their team is very
small and tight-knit. It's been very hard for big distributed shops to
migrate SCM from Envy to Store. I think that Cincom has provided consulting
support for that but I don't think they've provided any stats on the cost
or effort to migrate a typical project.
VA shops continue to use Envy as a supported and effective SCM but I
haven't used VA commercially, but I'm assuming it works for them.
It's not surprising that this old stuff doesn't get migrated given how IT
projects are funded in general. When you've got hundreds of Java servers
spewing errors all day, it's hard to get excited about some old Smalltalk
stuff that just keeps the business chugging along.
