Hello, I have recently taken over a subscription based Wordpress website with amember 3.1.9 implementation. I have read on forums and documentation that Upgrading from 3.x to 4.x is not a trivial task and all customization has to be redone again. Our site is working alright and on the face of it there does not seem to be any reason to upgrade. In light if this, would experienced members be able to help me with the following questions: 1. What are a few compelling reasons to upgrade? What would amember 4.x provide that cannot be done with 3.x - anything that will help make a business case for the upgrade? 2. Assuming that we plan to upgrade - what would be ballpark estimates time / effort required to do this? Are there any implementation partners who can help with this - and if so, what would be the cost of doing this? Thanks for your help.
