there wasn't a whole lot of change between SR1 > 2. Money increased slightly for some of the Priorities, and Magic got a tad more flexible. Attributes and skill points were the same, so direct transfers were pretty much fine.
The back of the
SR3 book has the conversion notes for SR 2 > 3. It is a little complex. It involved eyeballing your skills, to see which transfer over, which fit into new categories. Also, skill points Increased from Priority from 2 > 3, so you got (pool of points) - [what few knowledge skills you have] to spend on new Knowledges, and the amount you had already spent you got to add to Active Skills. Doesn't really say how to modify attributes, eben though the priorities provided a few more points on average, and since the attributes (Strength, Quickness, etc) didn't change, these were probably left the same, though you could probably add 3 points total (for all but Priority A)
The SR 3 > 4 was linked above, and the SR 4 > 5 guide is available free on Drivethru.
Ultimately between 3 and 4 skills and attributes are multiplied by .6667 (so they are a little lower), and Quickness and Intelligence are doubled and those points split between Agi/Reaction and Logic/Intuition respectively.
And between 4 > 5, Attributes don't really change, but Skill rating increase based on the chart - no real flat multiplier.. some numbers are x1.25ish, and some near x2.. so go by the chart.
