I'm trying to avoid the situation that develops when people don't really agree on 'house' rules and then characters and campaigns are not easily transferable among group GM's.
My group only agree to try 5 on the condition that we use only 'official' material.
Officially, then, don't worry about conversions. All conversions lie firmly in the realm of "a house rule." This is not a bad thing - house ruling 5e is pretty easy - but if it's a bridge too far for your group, just don't do conversions.
For those like me looking for a practical guide, though, this seems to do the job nicely. It tells you how to do it, and what traps to look out for. Solid.
