Skills

Starfinder has two skills not available in Pathfinder: Computers and Piloting. The Piloting skill replaces Driving Lore and Sailing Lore, and any archetypes, equipment, or feats that used these skills should use Piloting instead. While there's no direct analogue to the Computers skill, the GM might allow PCs to use similar skills, such as Occultism or Thievery, to accomplish similar tasks until they have an opportunity to gain proficiency in these skills. A GM should consider finding an opportunity for PCs built using Pathfinder rules to retrain skill proficiency choices into Computers or Piloting. Lore skills should be considered based on the theme of the campaign, and some specific lores players could gain from backgrounds and ancestry feats might not be applicable for use in a Starfinder campaign. Switching those to another vaguely related lore, such as Hellknight Lore instead of Cheliax Lore, or a broader lore, such as Golarion Lore or History Lore instead of Cheliax Lore, can help make the skill more relevant for your campaign.
