A recent survey of WaveMaker's 15,000 developers found that over 20% had moved to WaveMaker as an alternative to Microsoft development tools like MS Access and MS .NET.
"Microsoft shops" typically employ a variety of Microsoft products and have dozens to hundreds of applications that now need to be migrated.
Having worked with many companies going through this migration process, here are some best practices I have seen:
1. Triage, triage, triage - figure out which apps are really critical to your business/users and focus on them. Often, as you migrate them from Microsoft to WaveMaker you will find that you can combine several clunky client/server apps into a single rich internet application.
3. WaveMaker is a lot more productive - we find that MS .NET apps can typically be rebuilt in WaveMaker with 80%+ fewer lines of code. See the Nationwide video on the WaveMaker web site for a case example that resulted in 98% fewer lines of code! That translates to big savings in productivity and quality, both in development and maintenance.
4. Open is still a bit messier - even though WaveMaker hides most of the hard stuff, it can't hide all of it. Microsoft's great advantage is that everything is tightly integrated into one convenient but proprietary package. In contrast, WaveMaker integrates with many databases, report writers, etc, which is more flexible but puts more work on the developer to manage their environment.
In short, WaveMaker provides a much gentler path for migrating from the Microsoft Borg to the wonderful world of open standards, but there is still a cost for all that flexibility.
