Hmmm... I've had good luck just kind of spitballing things; much of the SR5 content is ported from SR4 anyway, albeit with (sometimes serious) changes. The one that my group hangs up on is the distinction between 4E "nodes" and 5E "hosts/devices."
The most obvious changes are budgetary; some things that were incredibly cheap in 4E (thanks, nanoforging techniques!) are now much more expensive in 5E (thanks, nanoforging techniques!). However, there's also a significant shift in the mechanic with the addition of limits, which you'll have to work around.
As for guidelines, hunt up the 4E -> 5E conversion guide; it won't cover all the bases, but it should help quite a bit.
