More than 93 percent of Lotus Notes customers are using the most recent two releases
So presumably almost everyone was on R6(which came out in 2003) and R7 and this perhaps ONLY included those paying for maintenance or support.
My luck I know the 7% on R5 but moved them to R7 and R8 this year.
Anyway, Microsoft in contrast, has about 25% or more still on Exchange 2000 which is now 2 revisions back. Did IBM get marketing right this time?
I posted about this previously here.
As a comparison, Exchange 5.5 came out in 1997, about 11 years ago.
Based on this article from 2005 this has been going on for some time with large chunks not willing to Migrate forward.
The difference between an upgrade and a migration varies but IMHO if can upgrade a software product in place with no extra hardware requirements(aside from RAM or Disk space) that is an upgrade. If I must move to a different platform or require middle man servers or other systems to complete this task, then it's a migration.
Then we have clients that have committed to Microsoft to move off of Lotus platforms, yet as Ed points out, not all have moved or if they have not entirely.
What if there is a correlation between these ideas. Can Microsoft, the epitome of a Marketing machine to those of us on the outside, not actually sell their own products to their own customers?
Perhaps Vista's marketplace issues really stem from a broader problem within Microsoft that has been hidden away for some time but now is leaking out. No matter how much money or stars they can strut in front of us, the problem may be an internal flaw.
Known for announcing something long before it sees the light of day, Azure for example is at least a year from general availability, could they be digging their own hole?
I have some ideas about what they can do, but why should I give them all of my free advice. I figure a potential market valued at $464,000,000! (Total is $1,856,000,000 based on this study from Microsft and Radicati) is worth something, don't you?
