i upgraded my vm1 store to vm2 using migration tool.
if now i use REMOVE VM DATA tool, will it delete vm2 data only or all data tables with old vm1 ones?
It should delete all vm2 data. Also when you use the reinstall tools, your vm1 data remains. This is done, because there existed (disabled atm) different methods to import your stuff. For exampel if you want to port the flypages or not.
