I'm planning to upgrade WHMCS from 4.5.2 tp 5 soon. The only hang up may be the VPS.Net module that I installed and modified. This was version 1.0 of their VPS.Net WHMCS module and an upgrade is available, but I attempted the upgrade yesterday. It didn't go well, so I went back to 1.0 for the time being.
So, if I upgrade WHMCS to vers 5, is it likely that this older module will still run as a Legacy Module or do I have to upgrade? Just wanted to know if anyone had experience using older modules in vers 5.
Thanks,
Mark
