Have FMP13 app.. update FMP19, addition Cloud

[RodM]

out of touch.. working now to update or rewrite?
 

Hello, i have this completed win7 32 bit FMPro 13 code & running  

if i update my FMP engine to version 19 will my app run DESKTOP STILL as is?   Partly run?   I know i have some code issues running windows 10 in 64 bit to debug

i choose to subscribe to Cloud

i am some what confused

Can i run dome my app in desktop and some portions using cloud ?

i have a large FMP 13 no need to put on Cloud but be nice to add cloud for some  remote FM USERS options

I will probably need more info

where do i start migration   Videos, here?

 

TIA
