Upgrade advice please, VC 2.3.2 to 3 with mf dialog

Hi there,

I have questions re. upgrading from VC 2.3.2 to 3 with mf dialog on VS 2015 community edition

(1) Can you clarify, is there a VC version 3 add pack for MF dialog system or is everything included?

(2) To install VC do I need to uninstall 2.3.2 first? Same question cobol server 2.3.2, addpacks and hotfixes on our production machines?

(3) Would you recommend upgrading at this point or should I wait until after the first hot fixes have been released? Is 3 considered stable?
