Upgrading from Syclo Smart Service Manager version 3.0 to 4.1
I am working on an application built on Syclo Smart Service Manager 3.0.
We have done 60% customization on the standard code.
Now the client is planning to move to Smart Service Manager version 4.1.
If we upgrade the application to 4.1 would it require all the customizations to be done again.
Or else can we convert 3.0 into 4.1 taking inspiration from it.
What is the best approach that should be taken?
Also what are the agentry server and client versions that will support SSM 4.1?
