Application migration from coldfusion9 to coldfusion2021

[Sumalini5D28]

Hi Team,

I am working on coldfusion9 application now we want migrate our application to coldfusion 2021 in this context we want to know

1. If we migrate our application coldfusion 9 to coldfusion 2021 do we need to do any code modifications after migration or simply migrating to Coldfusion 2021 does all the things? 
2. Because coldfusion 2021 has cloud support does our coldfusion 9 code will work in the cloud after migration..if it will work what are all the code & configuration level modifications we need to do?

Looking for your earliest reply.....

Thanks.....

It's very unlikely that migrating from CF 9 to CF 2021 "does all the things". You'll probably have to make some minor changes to your code here and there.

Your CF 9 code will work in the cloud, regardless of CF 2021's cloud support, because it doesn't actually use any of that cloud support. You can add that stuff to your code down the line. But you can run practically any version of CF in the cloud, on VMs, just like you'd run it on-premise.
