I have a question. You have changed version in first place I mean 1.00.0000 to 2.00.000 and applied major upgrade steps. If we change in second place I mean after first dot e.g. 1.20.0000 , in this case can we apply major upgrade steps and does it work like uninstall previous version 1.00.0000 completely and install latest version and files?
Yes you can change the second number also to create a major upgrade and it will work, however the best recommended method from Microsoft for creating a major upgrade is to change first number
