It’s been my experience you don’t need to run any incremental, just go for it. I once went from 1.3 to 4 something with no issues.

Hi All,

I am planning on upgrading our surgemail 5.0 server to 6.0. Does anyone know if a straight upgrade from 5.0 to 6.0 is possible? Do I have to upgrade to 5.3 before upgrading to 6.0?

Thanks,
Georgi
